Abstract:

A comparative analysis of vector control scheme based on different current control switching pulses (HC, SPWM, DPWM and SVPWM) for the speed response of motor drive is analysed in this paper. The control system using different switching techniques, are comparatively simulated and analysed. Ac motor drives are progressively used in high-performance application industries due to small size, efficient performance, robust to torque response and high power to size ratio. A mathematical model of ac motor drives is presented in order to explain the numerical theory of motor drives. The vector control technique is utilized for efficient speed control of ac motor drive based on independent torque and air gap flux control. The study compares the total harmonic distortion contents of phase currents of ac motor drive and speed response in each case. The simulation result shows that total harmonic distortion across the phase current in SVPWM is less as compared to other switching techniques while the rise time in speed response across SVPWM technique is faster as compared to other switching methods. The simulation result of ac motor drives speed control is demonstrated in Matlab/Simulink 2018b.

Abstract:

AC Servomotors are widely used in the industries for the control of static and dynamic loads. Precise control of position, speed, and torque are the main issues with the AC Servomotor. AC Servomotors are highly demanded by the industries to have a precise response under dynamic load conditions. Many control techniques are commercially available for the control of AC Servomotor under static and dynamic load conditions. However, all of these control techniques have advantages and limitations. Many investigations are done on the control of AC Servomotor, but comprehensive surveys on the control of AC Servomotor were still limited. In this paper, most of such commercially available control techniques are investigated, discussed, and compared.

Abstract:

This paper focuses on the simulation analysis of the conventional Internal Model Control (IMC) technique and the development of two proposed control techniques for the position control of AC Servo Motor. Internal Model Control (IMC) technique [1] was only able to control the AC Servo Motor under static load condition. Also, it had step response problems, and it was not robust against external disturbances. For these reasons, the IMC technique was further improved to control the AC Servo Motor under dynamic load conditions by proposing Amended Internal Model Controller (AIMC). The step response and the robustness of AIMC against external disturbances were further improved by proposing AIMC+FLC. Where a Fuzzy Logic Controller (FLC) is designed and connected with the AIMC.

Abstract:

It has been proven that fuzzy controllers are capable of controlling non-linear systems where it is cumbersome to develop conventional controllers based on mathematical modeling. This paper describes designing fuzzy controllers for an AC motor run mechanism. It also compares performance of two controllers designed based on Mamdani and Takagi-Sugeno with the conventional control scheme in a short track length, following a high disturbance. Fine and rapid control of AC motors have been a challenge and the main obstacle in gaining popularity in use of AC motors in robots actuators. This chapter reviews how use of intelligent control scheme can help to solve this problem.

Abstract:

A position control approach for direct-drive robot manipulators with permanent magnet AC (PMAC) motors is proposed. The conventional vector control architecture has been simplified by specifying the motor stator phase so that the rotating d-axis current is zero. The position control is designed to be an enhanced fuzzy PD controller, by incorporating two nonlinear tracking differentiators into a conventional fuzzy PD controller. The proposed control methodology is easy to implement, and exhibits better control performance than conventional control methods. Experiments conducted on a single-link manipulator directly driven by a PMAC motor demonstrate the validity of the proposed approach.

SVPWM technology applied in AC speed regulation system can not only improve the shortcoming of low voltage utilization in the pulse-width modulation (PWM) technology, but have little torque ripple and low noise advantages. In this paper, a SVPWM vector control AC asynchronous motor speed regulation system employing a core TMS320LF2407A-type DSP chip was presented, and simulated the speed regulation system by MATLAB SIMULINK. The obtained simulation results indicate that the proposed speed regulation system has excellent dynamic and static performance, thus SVPWM control technology of asynchronous motor based on DSP has been implemented.

This circumstance means that the problems of the AC motor (nominal power, synchronous speed) and gearbox (transmission ratio) become non-trivial and necessitate optimal selection to ensure the best functionality of the entire driving system. This study proposes an approach for the optimal choice of a specific AC motor (nominal rating, synchronous speed) and the transmission ratio of the gearbox by analyzing the entire system’s losses. The optimal selection of an AC motor ensures maximum energy efficiency for a specific transportation driving cycle.

Abstract:

The SCADA-based AC motor monitoring and control system is a three-phase induction motor monitoring and control system. Motor speed regulation feedback is obtained from the tacho generator which is connected to the pulleys. The SCADA program manages inverter and microcontroller communications so that the process of monitoring the speed of an induction motor is done through a computer. Induction motor speed regulation using VSD as an inverter functions to adjust the source frequency so that the motor speed can be adjusted. Communication between VSD, PLC and SCADA uses the MODBUS protocol to monitor the performance of the induction motor. The main equipment uses ATV12HU22M3 inverter and CQM1H PLC. The CX-Programmer and CIMON software function to manage and monitor in real time the system. The results of the induction motor settings can be adjusted with VSD speeds ranging from 0-50 Hz. PLC as master control and SCADA function as distance controller.

Abstract:

The double-fed control strategy for AC hoist motor is discussed in this paper. The AC/DC/AC power converter is adopted as main circuit. Three-phase neutral-point-clamped three-level rectifier is used as AC/DC link to realize unity power factor at grid-side, which reduces harmonic distortions. For the DC/AC inverter, three-level topology is used, which is controlled by stator-flux oriented vector control method. Meanwhile, energy flows in bidirectional way by back to back three-level power converter. The hoist motor control system obtains a high dynamic performance when stator side operating in unity power factor condition. The reliability and safety of hoist system is improved based on double PLC. The control system mentioned in this paper is being used to control a shaft hoist with a capacity of 260kW, and the power saving is remarkable.

Abstract:

The loop controller of double position fully closed makes the AC servo drive system acquire a very high position accuracy and speed following which is hard to be achieved for time-varying parameters, load disturbance, AC motors and severely nonlinear controlled objects. For the system, the dynamic nature can be ensured by the inner position loop adopting PI regulation of half closed loop structure, while the stability and the immunity can be achieved by closed loop structures with the rings outside adopting dual-mode fuzzy control. This article analyzes the cause of positioning errors for servo motor and semi-closed loop structure. The article also explains how to design a two position closed-loop servo system based on fuzzy control by adopting the AC servo motor drive, the motor shaft back-end incremental photoelectric encoder to form the inner position loop and using the motion control card, the inner ring of servo system and the work platform of grating ruler to make up the outer position loop. Based on double position loop composed of three-dimensional laser processing gear, the accuracy of the three-axis linkage workbench position control and the speed following can be ensured, thus meeting the requirement of the laser subsurface engraving machine for high speed and high precision motion.
