Abstract:

This paper summarizes a robust controller based on the fact that, in the operation of a permanent magnet synchronous motor (PMSM), a number of disturbance factors naturally occur, among which both changes in internal parameters (e.g., stator resistance Rs and combined inertia of rotor and load J) and changes in load torque TL can be mentioned. In this way, the performance of the control system can be maintained over a relatively wide range of variation in the types of parameters mentioned above. It also presents the synthesis of robust control, the implementation in MATLAB/Simulink, and an improved version using a reinforcement learning twin-delayed deep deterministic policy gradient (RL-TD3) agent, working in tandem with the robust controller to achieve superior performance of the PMSM sensored control system. The comparison of the proposed control systems, in the case of sensored control versus the classical field oriented control (FOC) structure, based on classical PI-type controllers, is made both in terms of the usual response time and error speed ripple, but also in terms of the fractal dimension (DF) of the rotor speed signal, by verifying the hypothesis that the use of a more efficient control system results in a higher DF of the controlled variable. Starting from a basic structure of an ESO-type observer which, by its structure, allows the estimation of both the PMSM rotor speed and a term incorporating the disturbances on the system (from which, in this case, an estimate of the PMSM load torque can be extracted), four variants of observers are proposed, obtained by combining the use of a multiple neural network (NN) load torque observer and an RL-TD3 agent. The numerical simulations performed in MATLAB/Simulink validate the superior performance obtained by using properly trained RL-TD3 agents, both in the case of sensored and sensorless control.

Abstract:

Three-phase brushless motors are an indispensable part of the industry. A significant portion of electricity consumption is the energy consumed by industrial motors. Therefore, these electric motors need to be used efficiently. If these motors are not driven by the suitable inverter, they cannot handle the load or increase losses in the energy. In addition, the system can be inefficient.  Since these motors have a high starting torque and controlling rotation speed is difficult, a better control method is preferred rather than a V/f control.                 This research aims to control using PMSM (permanent synchronous motor) FOC method and Space vector PWM with the position sensor, which is incremental encoder and. FOC approach, will minimize energy losses. Also, Space vector PWM method reduces the harmonic of the motor current. The FOC approach is to direct the stator rotating field most efficiently using the motor's rotor position information. The incremental encoder will provide the information rotor position and speed. The software structure is achieved through the utilization of a STM32F745VE that is new series Cortex™-M7 32 bit ARM® processor. FOC calculation takes 14.5 microseconds thanks to the Cortex M7 architecture and floating point unit

Abstract:

This paper presents the development of BLDC (Brushless DC) motor control based on dsPIC30F4012. The system is designed to control motor rotation in clockwise (CW) and counter clockwise (CCW) directions. There are 3 input pins used to facilitate the control interface, namely ground (GND) pin, control (CTRL) pin and enable (EN) pin. An analog input was assigned as command input for rotation in CW/CCW direction. The CTRL pin input has full-scale of analog input that comprises of three regions, namely CCW rotation input (0V~2.4V), CW rotation input (2.6V~5V), and neutral input (2.5±0.1)V as the deadband. The commutation sequences of six steps for direction of motor rotation, while P-I (Proportional-Integral) controller is used to control the motor current. The control law and commutation sequences are implemented in single chip dsPIC30F4012 microcontroller. To verify the system performance, we test the system implementation to drive BLDC motor and measured current are sent to the host PC through serial communication. From the experimental results it is shown that the realizing P-I controller is good performance in small frequency where the bldc motor current can follow the input commands. The bandwidth of motor control to characterize the performance of designed system is also presented.

Abstract:

PWM Switching Strategy for Torque Ripple Minimization in BLDC Motor This paper describes a new PWM switching strategy to minimize the torque ripples in BLDC motor which is based on sensored rotor position control. The scheme has been implemented using a PIC microcontroller to generate a modified Pulse Width Modulation (PWM) signals for driving power inverter bridge. The modified PWM signals are successfully applied to the next up-coming phase current such that its current rise is slightly delayed during the commutation instant. Experimental results show that the current waveforms of the modified PWM are smoother than that in conventional PWM technique. Hence, the output torque exhibits lower ripple contents.

Abstract:

As multi-object spectrographs (MOSs) continue to evolve, a notable trend has emerged—the increasing accommodation of fiber positioners on ever-more compact focal planes. This progression has seen the traditional stepper motors being supplanted by more space-efficient miniature hollow-cup motors. A significant challenge faced in the employment of these 4 mm diameter motors is the absence of compatible angle sensors, resulting in reliance on open-loop control methods for positioning. Addressing this challenge, this paper introduces a novel miniature angle sensor designed specifically for 4 mm hollow-cup motors, and presents a newly formulated closed-loop control scheme, which leverages this sensor to achieve accurate positioning. This marks the first implementation of an angle closed-loop control system within a 4 mm miniature hollow-cup motor used in MOS fiber positioners. Experimental evidence suggests that this sensored closed-loop mode substantially improves upon the energy efficiency and precision of fiber positioner placement, compared with traditional open-loop stepper control methods. Furthermore, the integration of these microsensors mitigates collision risks during the concurrent operation of fiber positioners by deactivating the motor power supply to prevent potential damage to the system.

Abstract:

This paper presents a novel scheme for fast fault detection and isolation (FDI) of position sensors based on signal processing and fault-tolerant control (FTC) for speed tracking of an electric vehicle (EV) propelled by a permanent magnet synchronous motor (PMSM). The fault is detected using a comparison algorithm between the measured and delayed rotor speed signals. The proposed scheme is more practical for diagnosing faults over a wide speed range since it does not use estimated speed value. In addition, to ensure continuous vehicle propulsion and to retain effective field-oriented control of the EV-PMSM in the event of a fault, a reconfiguration mechanism with back-EMF based position observer is employed. Rapid detection of position sensor failure is necessary for a seamless transition from sensored to sensorless control. Furthermore, a comparative analysis between sliding mode observer and flux observer for motor speed control is also presented in the context of EVs. The effectiveness of the position sensors for FDI and FTC is validated in the presence of typical vehicular disturbances, such as uneven road conditions and wind disturbance force. Finally, to validate the proposed approach experimentally in a real-world EV environment, this paper utilizes a scaled-down testbed with a TMS320F28379D DSP for the motor control of the EV.

Abstract:

Brushless DC (BLDC) motor is a three-phase motor that cannot work directly with DC current but requires electronic commutation to replace the brush function in DC motor. This paper aims to implement BLDC motor driver integration based on bootstrap circuit using Autodesk Eagle. The driver board consist of bootstrap circuit based on IR2110, MOSFETs, three voltage regulator, ESP32 microcontroller and ACS712 current sensor connection, logic level converter, and BLDC hall effect signal sensor conditioning. The research proposes bootstrap capacitor calculation based on charging/discharging capacitor principle and the minimum motor speed rotation. The implemented driver has 14x10 cm dimension tested to drive 24V/135W/6000rpm sensored BLDC motor using six steps commutation with pulse width modulation (PWM) inserted programmatically in ESP 32 to drive the high side MOSFET of the driver without AND gate circuit. The effect of pwm frequency and dutycycle variation to the speed and current of the motor is investigated. The results showed that the driver with both 12 V and 24 V voltage source and 68 μF bootstrap capacitor work optimally in 20 KHz PWM frequency both in open loop and closed loop speed control test. The motor reach 129 W for the largest power and 5250 rpm for the fastest speed in 24 V supply.

Abstract:

An in vitro simulation test using a designed well-targeted test rig has been regarded as an effective way to understand the kinematics and dynamics of the foot and ankle complex in the dynamic stance phase, and it also allows alterations in both internal and external control compared to in vivo tests. However, current simulators are limited by some assumptions. In this study, a novel foot and ankle bionic dynamic simulator was developed and validated. A movable 6-degree-of-freedom parallel mechanism, known as Steward platform, was used as the core structure to drive the tibia, with a tibial force actuator applied with different loads. Four major muscle groups were actuated by four sensored pulling cables connected to muscle tendons. Simulation processes were controlled using a software developed based on a proportional–integral–derivative control loop, with tension–compression sensors mounted on tendon pulling cables and used as real-time monitor signals. An iterative learning module for tibial force control was integrated into the control software. Six specimens of the cadaveric foot–ankle were used to validate the simulator. The stance phase was successfully simulated within 5 s, and the tibia loads were applied based on the body weight of the cadaveric specimen donors. Typical three-dimensional ground reaction forces were successfully reproduced. The coefficient of multiple correlation analysis demonstrated good repeatability of the dynamic simulator for the ground reaction force (coefficient of multiple correlation > 0.89) and the range of ankle motion (coefficient of multiple correlation > 0.87 with only one exception). The simulated ranges of the foot–ankle joint rotation in stance were consistent with in vivo measurements, indicating the success of the dynamic simulation process. The proposed dynamic simulator can enhance the understanding of the mechanism of the foot–ankle movement, related injury prevention, and surgical intervention.

Abstract:

En los últimos años, la contaminación del aire y la detección de gases nocivos se han convertido en una vertiente en la investigación. Por ello, hoy en día se han desarrollado diversos sensores capaces de detectar diferentes gases, por ejemplo, los sensores químico-resistivos y los de tipo metal-óxido-semiconductor (sensores MOX), los cuales se destacan entre otras tecnologías. Los sensores de gas MOX permiten detectar múltiples gases con una alta sensibilidad y además son compatibles con tecnologías de integración CMOS. Los sensores MOX combinan un elemento de sensado de gas y un elemento de calentamiento para la selectividad de gases. Actualmente, la modulación de la temperatura de operación es una de las técnicas más usadas para mejorar la selectividad y estabilidad de los sensores de gas MOX. En este trabajo se propone un circuito de control on/off para la modulación de la temperatura de operación de sensores MOX utilizando la resistencia del calentador para monitorear su temperatura. Este circuito permite aplicar diferentes técnicas de modulación de temperatura tales como la técnica de modulación por pulsos, la técnica de modulación por ondas periódicas y el control a diferentes niveles de la temperatura de operación para la generación de matrices virtuales de sensores mediante un solo sensor. El circuito se diseñó en una tecnología CMOS de 180nm y se simuló usando un modelo simple del sensor comercial AS-MLC de AppliedSensor. El circuito propuesto permite alcanzar exactitudes de 0.2 Ω en el valor de la resistencia del calentador, el cual, corresponde aproximadamente a un error de 1 °C en la temperatura de operación del sensor.

Abstract:

Backgroud: Limitations in a radiographic projection of the Left lateral decubitus (LLD) ussually challanges most of the Radiografers who intent to apply the technique toward patients with acute abdoment clinical cases. Related problems that occasionally come up with the LLD projection are the fixed patient positioning and the waiting time it takes to keep patient in the same position. The poor quality of the LLD radiograph and less imaged optimalisation of the free-air below the right diapragm lead to a dificult radiological interpretation. The study aims to design an aided patient fixation tool with its controlling timer used for the LLD projection; and to examine the the functional performance of the tool.Methods: the research is qualitative approached with an experimental study. Several steps following the reseach are creation of the master plan designs and selection of materials that should be used to develop an appropriate aided patient fixation tool with controlling timer for LLD projection; evaluation of the 5 designed tool system components (seated patient, cassette holder, safety belt, electronic sensored movement, andthe timer); and qualitative testing of the tool function and veryfication. The 6 aspects of tool performances have been decided to be complianced indicators whereas 5 observers (expert Radiographers) blended in the evaluation of the aided tool, and the tool has firmed to meet its requirement if the total observer’s score is greater and equal to 2,00Results: In general, the resulted tool perfomance testing fulfilled the requirements of the tool functions as it used for some radiographic procedures of the acute abdoment-LLD projection. The tool performance scores of convenince and reliability equipment showed at 2,25 and 2,75 which meant that a general radiographic quality was looking good without any presense of the artifacts. Morover, the scores for timer and censored devices were 2,70 and 2,65 recpectively, by this clearly described a proper function of timer control and indicator components. The total score for radiation safety evaluation contributed to the higest score amongst all aspects being assessed that was 2,80.Conclusion: The design of the aided patient fixation tool with controlling timer for LLD projection has not only met functional requirements but it has also proven to subtitute some limitations about maintaning good image quality when applied the LLD projection. Radiologic expertation on the LLD-radiograph of the acute abdoment obviously contributed to optimal clinical information

Abstract:

Processos industriais geralmente necessitam de algum tipo de controle, podendo ser manual ou automatizado. O controle é feito em alguns parâmetros como vazão, temperatura, concentração, e controle de nível. O controle de fluxo é mais utilizado nas saídas ou entradas de tanques, controlando a concentração exigida naquele recipiente. Este trabalho teve como objetivo desenvolver um módulo de controle de nível em escala piloto, que poderá realizar o controle de maneira automática, e verificar a reprodutibilidade dos sensores e atuadores com a intenção de fixar o conhecimento já adquirido e disponibiliza-lo para ser utilizado na formação acadêmica profissional de outros estudantes de engenharia. O módulo foi projetado, construído e instalado, e foram realizadas curvas de calibração para os sensores de vazão e os sensores de pressão, e foi analisada a vazão máxima para a operação do módulo. Obteve-se como resultado uma dependência linear entre a tensão (mV) e a altura da coluna d’água do módulo. Observou-se uma dependência linear entre a frequência (Hz) e a vazão de líquido do módulo. A vazão máxima de operação determinada experimentalmente para o módulo desenvolvido é de 7,3 L.min-1. As calibrações dos sensores de pressão e de fluxo demonstraram que todos os sensores apresentam reprodutibilidade na faixa de operação a ser usada.

Abstract:

Este artigo descreve um sistema de monitoramento e controle para tanques industriais, focando na medição precisa do nível do tanque e na qualidade do líquido armazenado. Utilizando sensores ultrassônicos para medir o nível do líquido, sensores de temperatura para monitorar variações térmicas, e sensores de gás para detectar possíveis contaminações, o sistema proporciona uma visão abrangente das condições do tanque. Os sensores são compatíveis com a arquitetura Arduino. Os dados coletados são processados em tempo real e exibidos em um dashboard, permitindo aos operadores monitorar e controlar os parâmetros com alta eficiência. Os resultados indicam que o sistema alcançou um nível de precisão de 95% na medição e análise dos dados. Além disso, o tempo de resposta para a entrega das informações ao usuário foi inferior a 2 segundos, garantindo decisões rápidas e bem-informadas. Essas características tornam o sistema uma solução robusta e eficaz para o gerenciamento de tanques industriais, promovendo uma operação mais segura e eficiente.

Abstract:

En este artículo se desarrolla una ley de control para navegación autónoma en interiores basada en la detección visual de marcadores de referencia. Técnicas de estimación de pose externas como la localización por GPS o sensores RGB-D en techos son complicados de implementar en entornos cerrados donde puede haber obstrucci´on de vista o señal, como en almacenes, por lo que la estimación de pose local con sensores a bordo presenta una solución más viable. La implementaci´on de cámaras web de alta definición supone una solución más económica que el uso de sensores de alta calidad como sensores láser tipo Lidar. En la ley de control diseñada se considera a un marcador visual ArUco en su campo de visión, como un marco referencial inercial local. Con base en los errores medidos por odometr´ıa es posible ejecutar la tarea de regulación hacia éste marcador.

Abstract:

Abstract The manipulation of flexible endoscopes is a procedure that requires great dexterity since it requires the synchronization and use of both hands in parallel. Imprecise handling during gastroendoscopy could harm the digestive tract. Our solution allows the physician to use only one hand to wirelessly control the forward, backward, and tip bending motion. The proposed system provides endoscopic vision and tactile impact force sensing at the tip to detect the force applied to tissue and thus avoid damage. We experimentally evaluate the handling of the robotic system in open space and inside a medical phantom. The results revealed a training effect with less time demand for task completion and reduction of average impact force after only 5 runs. The proposed system was successfully controlled using one hand and, together with the force information, could enhance the physician’s experience during endoscopy. Future work will address axial control and an intensive user study with clinical experts.

Abstract:

El monitoreo de la calidad del agua es un aspecto crítico para garantizar agua segura y limpia para el consumo humano, los procesos industriales y la vida acuática. El empleo de sensores automáticos basados en el internet de las cosas y algoritmos de aprendizaje de máquina utilizados para el monitoreo de la calidad del agua se ha vuelto cada vez más popular, debido a su facilidad de uso, precisión y rentabilidad. En esta revisión, discutiremos algunos de los sensores comúnmente utilizados para la vigilancia de la calidad del agua, así como sus posibles usos para la gestión y supervisión de acuíferos en América Latina. En la primera parte se discute sobre la contaminación de las fuentes de agua en Latinoamérica y, especialmente, en República Dominicana, donde se brinda una revisión de los diferentes trabajos que evalúan la contaminación en afluentes de agua. Además, se explora como el uso cotidiano de estas fuentes de agua puede afectar a los seres humanos. En la última parte del trabajo se presentan las tecnologías de los sensores y sus diferentes implementaciones, así como los principales retos para su integración al monitoreo de la calidad de agua de las fuentes de agua. Esta revisión demostró que el uso de sensores remotos de calidad de agua, basados en tecnologías de IoT y algoritmos de inteligencia artificial son de gran importancia para el control de la contaminación fisicoquímica en los acuíferos de los países latinoamericanos. Estos sensores constituyen una herramienta clave para el manejo sostenible de los recursos hídricos.

Abstract:

El actual avance tecnológico mundial y el crecimiento e las comunicaciones, ha hecho necesario que la información que generan diferentes dispositivos, en especial aquellos que disponen de sensores, esté disponible de forma inmediata para poder dar respuestas y/o soluciones dependiendo de los eventos que pudieran presentarse. El desarrollo de esta área en los últimos años ha provocado la aparición de dispositivos con sensores de tipos y marcas heterogéneas. El presente artículo presenta una propuesta de arquitectura que integra varios servicios web estándares para la recopilación, organización, y almacenamiento de la información proveniente de sensores hidrometeorológicos. Igualmente se propone la aplicación de servicios para el control remoto de los sensores y para la gestión de eventos y generación de alertas. Todos estos servicios web forman parte del estándar Sensor Web Enablement (SWE). Considerando la diversidad en las estaciones y sensores hidrometeorológicos que típicamente se encuentra en una red de monitoreo, se propone en este artículo la aplicación de ontologías para homogenizar e integrar la información proveniente de sensores de diferentes tipos y fabricantes.

Abstract:

O presente trabalho teve como objetivo desenvolver um circuito e um sketch para dois sensores de temperatura DS18B20 capazes de monitorar a temperatura em tempo real durante o processo fermentativo de leite por grãos de kefir em um biorreator de bancada utilizando a plataforma de prototipagem Arduino UNO R3. O primeiro passo foi o desenvolvimento do circuito e do sketch com base na literatura e para isso foi utilizado um Arduino UNO R3, dois sensores DS18B20, um Display LCD (20x4), cabos jumpers, uma protoboard e dois resistores (4,7 kΩ). Posteriormente, foi feita a adaptação dos sensores ao biorreator. O circuito e o sketch desenvolvidos foram capazes de captar os sinais elétricos apresentados pelo sensor e convertê-los em valores de temperatura (ºC), sendo estes valores impressos no display LCD e no Monitor Serial (computador). Os valores de temperatura exibidos pelos dois sensores apresentaram uma diferença de aproximadamente 0,2°C, estando dentro da faixa de erro do sensor apresentada pelo fabricante. Os sensores DS18B20 foram posicionados dentro do biorreator a partir de dois tubos de aço inox inseridos próximos da parede do biorreator com alturas distintas para medir a temperatura no fundo do biorreator e na superfície do fluido.

Abstract:

Los algoritmos de navegación de robots móviles usan sistemas de control de posición para ejecutar tareas como la exploración, seguimiento de trayectorias, búsqueda y rescate, entre otras. Sin embargo, la implementación de estos algoritmos involucra sensores como los GPS, cuya precisión depende de factores externos como los climáticos, así como su funcionamiento puede verse afectado por la disposición de satélites, generando errores de posición. Como solución a lo anterior, en este trabajo se propone un sistema de control basado en fusión de sensores mediante el filtro de partículas que permita mejorar la navegación de un robot móvil tipo rover, consiguiendo una mayor precisión en la navegación, reduciendo la vulnerabilidad del sistema, incrementando la confiabilidad y la tolerancia a fallos y un aumento en la confianza en las mediciones. Finalmente, se muestran los resultados de la fusión de 5 sensores, el modelo cinemático del robot y el control PID de posición para un recorrido desde una posición inicial a una final.
