Abstract:
Chinese spinning technology has developed for more than 40 years. Especially in recent years, various kinds of spinning equipment have been developed and contributed a lot to Chinese equipment manufacturing industry, but it is blank in the light industry and civil industry. Due to the high cost and programming complexity of NC machine tools, we have no dedicated spinning machine and mostly rely on simple manual in the lampcover production. As to the above problems, we developed the lampcover NC spinning machines that can generate the track automatically and complete automatic control in the machining process.

Abstract:
The modern development of the food industry is accompanied by an ever wider application of automated control systems for technological processes. The prerequisites for this are: the growth of the enterprise's capacities; the use of continuous and continuous production methods; equipment of enterprises with new high-performance equipment; presence of modern technological means of automation. The wide application of automated control systems is caused by a significant economic effect, which is achieved due to: the provision of specified qualities of produced products, regardless of subjective factors; reduction of losses of valuable products; reduction of labor intensity of production processes; increase of production culture. The main task of the automated control system is the observance of the technological regulations determining the permissible ranges of technological process parameters (temperature, flow, product composition), equipment performance, and quality process indicators. In addition, the tasks of controlling installations and lines include their starting and stopping, emergency protection and interlocking. In order to carry out the tasks of automated control of installations and technological lines, it is necessary to gradually remove the human operator from the control loop and transfer the control functions to the technological means of automation. At the same time, the operator must monitor the operation of automation devices and make decisions in complex situations. Modern sugar production is a complex technological process. Therefore, ensuring the uninterrupted operation of the production line, maintaining its high productivity, obtaining a product of the highest quality is the most urgent task in this area.

Abstract:
Model-Free Adaptive (MFA) control is a technology that has made a major impact on the automatic control industry. MFA control users have successfully solved many industry-wide control problems in various applications and achieved significant economic benefits. Now, the challenge is extending the many advantages of MFA control technology to diverse and fragmented markets, which could benefit from its unique capabilities. Since single-loop MFA controllers can directly replace legacy PID controllers without the need for "system" redesign (plugand play), they are readily embeddable in various instruments, equipment, and smart control valves. This alleviates concerns relative to cost of change and also makes MFA an appealing tool for OEM applications on a large scale.

Full text
Abstract:
This thesis describes a multi-channel millimeter wave radiometer control system that will be used for atmospheric water vapor and temperature profile retrievals. The system consists of four subsystems which provide a total of nine frequency channels, a steerable reflector to permit slant-path measurements at different zenith angles, and a host computer for analyzing the data. The nine channels span the water vapor and oxygen absorption lines in the 20 to 60 GHz range. A distributed processing architecture is implemented to control the system. Each of the subsystems employs a signal processor and a microcontroller, which are configurable from the host. The signal processor filters the receiver's output, while the microcontroller oversees the radiometer, accepts data from the signal processor and communicates with the host. The host executes a custom shell that allows it to concurrently accept data from the subsystems, position the reflector and execute user analysis programs.

Full text
Abstract:
The purpose of this research was to develop three real-time adaptive temperature controllers for hyperthermia heating systems. Each scheme is made adaptive by using a transient Gaussian estimation routine to estimate the tissue blood perfusion and by then using these estimated values either in an optimizing routine, or in an observer, or in both. The optimizing routine uses a steady-state Gaussian estimation technique to optimize the power distribution until the best possible match is obtained between the steady-state temperatures predicted by a treatment model and a prespecified ideal temperature distribution. The observer uses a treatment model to control unmeasured locations. The first adaptive control scheme uses the optimizing routine alone, the second uses the observer alone and the third uses both the optimzing routine and observer. The performance of each of the adaptive control schemes is compared to a standard proportional-integral-derivative (PID) control scheme for one-dimensional simulations of typical treatments. Results comparing the deviation of the controlled temperature distribution to the ideal desired temperature distribution for all locations and all times indicate that the adaptive schemes perform better than the PID scheme. It can be concluded that adaptive control yields improved performance if good a priori knowledge of the treated region tissue and perfusion region boundaries is available. While these control schemes were designed for eventual implementation on a scanned focused ultrasound hyperthermia treatment system, the techniques are applicable to any system with the capability to vary specific power with respect to location and with an unknown distributed energy sink proportional to the temperature elevation.

Abstract:
Thesis (MTech (Information Technology))--Cape Peninsula University of Technology, 2007<br>The increasingly sedentary lifestyle of the past 30 years has contributed to declining health. Consequently, exercise is vital for good health maintenance. The global Health and Fitness Industry repeatedly indicates the need for optimally managed exercise with accurate information feedback. Compared to other industries, the fitness industry is lagging behind in incorporating Information Technology into its operations. On the other hand, the most current exercise equipment impose fixed-trajectory exercise on users with the dominance of static equipment designs. These exercise equipment are normally deadweight-based equipment. In deadweight-based exercise equipment, the weights generally can be changed only when the equipment is inactive. Therefore, a more novel exercise environment is required for current exercisers in the fitness industry. This thesis explores to develop a computer-controlled pneumatic dynamic resistance exercise equipment with onboard data management. This new technology optimises exercise effectiveness for users. Exercisers will have advanced diagnostic capacity, and will capture user data which can be manipulated into meaningful information for use by Health and Fitness Industry stakeholders. This thesis will explore all the key concepts about computer-controlled equipment. The key concepts to be investigated will include FX (force-displacement) control technology, pneumatic system control, fail-safe mechanics, and Graphical User Interface design. The primary aim of the project is to replicate and enhance the functionality, performance, and sensation of deadweight-based equipment. A further aim of the project is to investigate the feasibility of designing a compact retrofit-able pneumatic unit to replace the deadweights of existing standard exercise equipment. The computer control will be implemented on a "National Instruments PXI" computer featuring Data Acquisition and Control (DAQAC) capacity, and the software will be implemented using "LabVIEW 7.0', which is a graphic object-oriented computer language developed to facilitate hardware I software communications.

Abstract:
The German joint project GALILEOnautic aims to develop systems for autonomous navigation and optimised manoeuvring of vessels cooperating in areas with high safety and efficiency requirements, such as harbours or narrow waterways. In the conception of this project, the SAE levels of the automotive industry were applied for classification of intended levels in automation of already being used manoeuvring vessels. It fairly soon became apparent that the conditions in development of new autonomous road vehicles and the appropriate infrastructure are significantly different in comparison to adaption of navigation and manoeuvring of watercrafts which are part of a complex transport network. Therefor and in relation to the few orientating guidelines addressing autonomous maritime applications, a specific concept for manoeuvring automation in high safety areas was developed. It defines the automation levels towards autonomous shipping considering the current practice and the technical equipment on such vessels, the legal framework for automatic shipping as well as the requirements for integrating automatic manoeuvring in the traditional shipping traffic. The contribution introduces this automation concept and the necessary infrastructure for each level. Additionally, the results of the first project phase are presented. It implies the essential sensor equipment and subsequent data fusion to describe completely the dynamic ship motion and to recognise the close surrounding of the vessel. A hybrid control scheme is applied including feedforward and feedback modules. The control approach is illustrated by interfered encounter situations in ship handling simulator and for unmanned surface vehicles. The paper gives a prospect on the future investigations for higher manoeuvre automation.

Abstract:
Abstract Digitalisation and automation can account for massive efficiencies in wells operations. Managed Pressure Drilling (MPD) and Automated Well Control are examples of "smart" technologies that can mitigate risks and costs associated with drilling wells. The Automated Well Control system was developed to monitor the well, identify an influx, take control of the rig equipment and shut in the well. MPD provides annular pressure control, real-time information of the well parameters and conditions downhole and very accurate and immediate influx detection. However, if a high intensity influx is taken that exceeds the pre-planned operational limits of the MPD package, then secondary well control is required. Therefore, a combination of Automated Well Control and MPD has been developed to deliver both pressure control and well control in a safe, efficient and less error-prone manner. On an MPD operation, the Automated Well Control system shuts-in the well as soon as it is required to do so. With Automated Well Control in MPD mode, the MPD system decides when to shut in and the Automated Well Control technology will immediately space out, stop the mud pumps and top-drive, and shut in the well using the pre-selected blowout preventer. This interface between the two systems mitigates drilling hazards using automation. The sensitivity of MPD, combined with Automated Well Control technology enables fast identification, decision making and reaction to well control events. Consequently, this fully integrated solution improves safety and operational efficiency. The MPD and Automated Well Control systems were integrated into a test rig and several tests were efficiently performed. The tool enabled immediate action in the event of influxes, providing a valuable solution for the industry. This paper briefly describes MPD and Automated Well Control and summarises the interface between the two technologies, detailing how the integrated system works on a rig. Moreover, rig trialling results and further developments are presented.

Abstract:
Construction, earthmoving, and agricultural equipment manufacturers are moving toward building more and more equipment with electro-hydraulic control systems. The existing industry practices for the design of control systems in construction machines primarily rely on classical designs coupled with ad-hoc synthesis procedures. Such practices lack a systematic procedure to account for unavoidable plant uncertainties in the design process as well as coupled dynamics of the multi-input multi-output (MIMO) configuration. In this paper, an H-infinity loop shaping control design method is applied to a wheel loader with an electro-hydraulic control system. This tracking control design is used to provide an automatic bucket levelling feature for a wheel loader. A MIMO nonlinear model for an electrohydraulically actuated wheel loader linkage is considered. The robustness of the controller design is validated in simulation using a complete nonlinear model of the wheel loader linkage. The simulation results are presented for both an H-infinity loop shaping design and an LQG design. The LQG design is from previous work and presented here for comparison. The effects of varying fluid parameters such as bulk modulus are considered in a robust stability analysis. The stability robustness and performance are compared for the two controller designs.

Abstract:
Abstract Objectives April 2010 in the Gulf of Mexico and January 2017 in Oklahoma brought into sharp focus what can happen if the oil and gas industry gets well control wrong: 16 fatalities, significant environmental damage, loss of assets and reputation. Each year we have multiple blowouts and several fatality events due to a loss of well control. The oil and gas industry can improve from a personnel safety, environmental and reputation perspective. The Automation of Well Control will bring a significant step change in the area of Process Safety forwells. It prevents blowouts, reduces all influx volumes, minimising kicktolerance volumes and reducingcasing and well costs. Method A system has been developedwhich enables Automated Well Control whilst in drilling mode. Pre-determined influx rates, agreed by the operator and drilling contractor, and input by the driller are established. Once the system detects the influx, it performs a series of operations by taking control of the drilling rig equipment. The drill string is spaced out, top drive and mud pumps are stopped, and the BOP is closed. All of this occurs without the driller doing anything; however, he can intervene at any moment. Thissystem is designed as an aid to the driller and does not remove his responsibility. Results The Automated Well Control system has been tested on drilling simulators with real drillers. Comparisons tests have shown that the technology enables shut-in times faster than conventional human interface methods, with influx volumes typically 10-20% of those experienced during manual shut-in. Additionally, a full Field Trial using a traditional rigdemonstrated the effectiveness of the system, proving up the functionality under different operational requirements. The system can now be applied to any type of rig worldwide. Over 50 potential modules have been identified. Planned developments forthe system include circulatingout the kick automatically, shut-in for tripping, circulating, cementing and in-flow testing. It provides assurance for afast, safe and effective shut-in.A full Technology Qualification process has been used for this technology. Innovative Technology Over the past 20 years, technology advancements associated with simulators and cyber-rigs have enabled new technologies to be developed. One of these technologies is Automated Well Control. It is believed that this innovative system will enable a step change in the performance ofprocess safety forwell control, dramaticallyreducing major accident hazards, thereby saving millions of dollars per well, reducing environmental impact and preventing loss of life.

Abstract:
Abstract Drilling a directional well becomes an essential process in the oil and gas industry to ensure better reservoir exposure and less wellbore collision risk. In the high-volume drilling market, cost-effective mud motors are dominant. The motor is capable of delivering the desired well curvature by switching between rotating and sliding operations. Therefore, to follow a predefined well trajectory, it is a critical mission to determine the optimal operation control sequence of the motor. In this paper, a method of training an automatic agent for motor directional drilling using the deep reinforcement learning approach is proposed. In designing the method, motor-based directional drilling is framed into the reinforcement learning with an automatic drilling system, also known as an agent, interacting with an environment (i.e., formations, wellbore geometry, equipment) through choices of controls in a sequence. The agent perceives the states such as inclination, MD, TVD at survey points and the planned trajectories from the environment, and then decides the best action of sliding or rotating to achieve the maximum total rewards. The environment is affected by the agent's actions and returns corresponding rewards to the agent. The rewards can be positive (such as drilling to target) or negative (such as offset distance to the planned trajectory, cost of drilling, and action switching). To train our agent, currently, a drilling simulator in a simulated environment is created with layered earth model and BHA directional responses in layers. Other attributes of the drilling system are assumed to be constant and handled automatically by the simulator. The planned trajectory is also provided to the agent while training. The directional-drilling agent is trained for thousands of episodes. As a result, the agent can successfully drill to target in this simulated environment through the decisions of sliding and rotating. The proposed workflow is known as the first automated directional drilling method based on deep reinforcement learning, which makes a sequence of decisions of rotating and sliding actions to follow a planned trajectory.

Abstract:
With the advances in platform automation and the publication of NAN 06/2018 - Software integrity (previously NAN 02/2016), there has been a drive towards compliance to IEC61508 in the naval domain. Over the last few years Frazer-Nash have conducted a number of Original Equipment Manufacturer (OEM) audits and assessments to determine whether the requirements for safety critical software development in IEC61508 have been followed for a specific system or if a supplier's development processes are in line with the aspects of the standard which focus on software development, namely Part 3 - Software requirements. These audits have revealed some common problems across suppliers and highlighted that IEC61508 requires both organisational safety management processes as well as those specific for a system. As the naval industry looks to adopt the processes outlined in IEC61508 or an equivalent standard, this paper will present some of the lessons learnt from our IEC61508 assessments and offer some advice for new and existing suppliers. The paper will highlight some of the issues going forward as the development of safety critical systems is not a new concept but the specific factors arising in the naval domain from operating in variable environments, changing safe state conditions and ever increasing function complexity, present a key challenge. Included in the paper will be a view on how other industries are tackling IEC61508 compliance and where the strategies that have been adopted may be applicable in the naval domain as well as new tools which could assist with the development of safety critical systems.

Abstract:
The U.S. electric utility industry continues to undergo dramatic and accelerating transformation. Reliability and resiliency are a key focus. A number of important issues including cyber and physical security challenges, aging infrastructure, and low natural gas prices continue to be of concern. Significant advances in technology, and prolonged regulatory uncertainty are also contributing factors. Electric utilities are now making substantial investment in renewable resources and other technologies needed for renewables integration. This means a reduction in investment in generation assets and an increase in the transmission and distribution grids. There is also increased investment in providing customers with solutions to lower their costs, reduce their carbon footprint and provide control over their energy management. The transformation ultimately demands significant increases in power plant generation operating capabilities and higher levels of equipment reliability while reducing O&amp;M and capital budgets. Achieving higher levels of equipment reliability, with such tightening budget and resource constraints, requires a very disciplined approach to maintenance and an optimized mix of the following maintenance practices: • Preventative (time-based) • Predictive (condition-based) • Reactive (run-to-failure) • Proactive (combination of 1, 2 and 3 + root cause failure analysis) Preventive maintenance (PM) is planned maintenance actions taken to ensure equipment is capable of performing its required functions. PM tasks are generally time-based, depending on the availability of condition monitoring data through a predictive maintenance (PdM) program. Traditionally, PdM is largely performed by maintenance technicians in the field with handheld devices. Resource constraints usually mean that often weeks or even months elapsed between readings on the same piece of equipment. This approach has limitations with data volume, velocity, variety, and veracity. Significant recent advances in sensor and technology associated with the Industrial Internet of Things (IIoT) have enabled the transformation of critical power plant assets such as steam turbines, combustion turbines, generators, and large balance-of-plant equipment into smart, connected power plant assets. These enhanced assets, in conjunction with analysis and visualization software, provide a comprehensive on-line conditioning monitoring solution that enables both a reduction in time-based PM tasks and also automation of PdM tasks. This paper describes an approach by Duke Energy to apply smart, connected power plant assets to greatly enhance its fossil generation equipment reliability program and processes. It will outline the value that is currently being realized and will also examine additional opportunities.

Abstract:
Wildlife damage management (WDM) is an exciting field with many opportunities to provide solutions to the complex issues involved in human-wildlife interactions. In addition, WDM wildlife control operators (WCO) face a variety of threats to their physical well-being. Injuries can result from misused, faulty, or poorly maintained equipment, inexperience, mishandled wildlife, harsh weather, and dangerous situations, such as electrical lines. The goals of this publication are to: Develop an awareness of safety issues and adopt a mindset of “Safety First”, Review the major safety threats that WCOs face, Provide basic information for WCOs to protect themselves, and List resources for further information and training. Work in WDM poses many safety risks to those involved. Awareness, planning, and deliberate action can eliminate or reduce many threats. As the industry continues to develop, WCOs must keep up with new threats and safety practices to maintain their well-being. Following safe work practices helps to ensure WCOs remain on-the-job and injury free.
