(NC) machine tools, which are automatically operated by encoded (digital) commands, are capable of machining components with quality and quantity. Manufacturing industry heavily depends on these machines. Many different control architectures have been adapted in today&rsquo
s CNC technology. Centralized control system is quite popular in industry due to its ease of implementation. If the number of controlled axes on a CNC machine tool (>
3), increases so does the computational burden on the central processors. Hence, more powerful processors are needed. An alternative architecture, which is not commonly used in CNC technology, is the decentralized (distributed) control. In this topology, the tasks handled by the distributed controllers that are interconnected to each other by a communication network. As the need arises, a new controller can be added easily to the network without augmenting the physical configuration. Despite its attractive features, this architecture has not been fully embraced by the CNC industry. Synchronization among the axes in the coordinated motion is proven to be quite challenging. In this thesis, alternative distributed controller architecture was proposed for CNC machine tools. It was implemented on a 3-axis CNC milling machine. Open-loop control performance was investigated under various conditions. Different communication protocols along with different physical communication interfaces and a number of controller hardware were devised. An industry-standard network (RS-485) was set up by interconnecting these distributed controllers. Different data transmission protocols were devised in order to establish appropriate communication methods. Also, computer software (a.k.a. graphical user interface), which can coordinate the interconnected controllers, interpret NC part programs and generate reference position data for each axis, was designed within the scope of this thesis.

Axiomatic Design is presented as a scientific methodology in designing a complex machine control system. As an example, the CMP a machine control system is developed using the Axiomatic Design framework. The machine is a type of semiconductor processing equipment, which requires numerous actuators and sensors and the intelligent control of them to planarize thin layers of wafers. Signal processing modules, control algorithms, sequential process steps, graphical user interface, process recipe editor and the overall control system structure are all designed by the Axiomatic decomposition. Axiomatic Design is proved to be a very effective tool in control system development. It took less than six months to develop the system and the control system is fully functional without any major error or mistake. The resulting system is clear to understand, easy to maintain and upgrade, and flexible for further development and integration. Although the development has been specific to the CMP cc machine, the control system structure and the design methodologies presented in this thesis are universally applicable to the development of any type of machine control system.

Der volle Inhalt der QuelleIn this master thesis a flexible manufacturing system for a PTC machine hall has been modelled and simulated using RobCad. This system includes several equipments and machines which have been modelled and arranged to come up with three possible layouts. The machine hall in UW will be moved to a new place in Innovatum (a research area in Trollhättan). The machines were chosen from the existing machine hall according to UW requirements in order not to buy new machines because of economic reasons. The number of cells was also set by UW. The machines and equipments that will be moved are; two CNC machines, three ABB robots, a 4-axis gantry robot which transport the materials between the cells and a conveyor or a flex link which has been proposed in this project for the loading/unloading station use. The purposes of moving the machine hall to Innovatum are: - More people will be able to use the machine hall (i.e. UW, other schools and costumers from other companies for training purposes). - The environment will be more available to do more production operations using the robots and machines. - It will be a good opportunity to develop the programs and software, for that will let UW be able to hire a whole automation package to the costumers. - Students will be nearby to the industries'9 environment and may have more contact with different companies. - Since the new machine hall will attract costumers it will gain incomes to UW. Three layouts have been proposed in this thesis work, and these layouts fulfil all or most of the requirements of the costumers and users.

Der volle Inhalt der QuelleThe linear graph method is selected to derive comprehensive models of three electrohydraulic actuation subsystems, i.e. the swing, boom and stick subsystems, on the vehicle based on modelling of individual components. A new approach is proposed, then, to integrate rigid-body dynamic models with the actuator dynamic models to result in a complete machine model.
Off-line parameter identification procedures are used, including the least-square method. A series of experiments is performed to obtain numerical values for the parameters involved in the system models. The experimental setups are described in detail and new procedures are explained. The model validation studies show that the mathematical models closely represent the dynamic characteristics of the forestry machine.
The concept of coordinated control in teleoperation is studied. The resolved motion rate control strategy shows superiority over conventional joint-based control in heavy-duty forestry machines. Two inverse Jacobian manipulator control schemes, based on velocity and on position servo schemes, are introduced and evaluated under various operating conditions. The results provide guidelines for the design and implementation of manipulator controllers on a forestry machine.

Commercial nuclear technology today is facing challenges due to both economic viability and concerns over safety. Next-generation reactors could potentially improve with respect to both concerns through recent advancements in computation and machine learning, through autonomous control systems which minimize human error. The MIT Graphite Exponential Pile (MGEP) has been selected as the basis of a realworld demonstration of such a system, because of its simple properties and inherent safety. This study evaluated the preliminary feasibility of an autonomous control system for the MGEP through two parallel avenues; a practical investigation of various machine learning algorithms applied to fission systems, as well as the design and fabrication of a control rod for the pile. It was found that Convolutional Neural Networks (CNNs) outperform Support Vector Regression (SVR) in predicting the MITR power-shape. Additionally, acceptable results were achieved when applying the CNN algorithm to the MGEP to predict the flux distribution of its fuel elements. Finally, it was verified that neutron detectors in the pile respond predictably to control rod insertions. Taken together, the groundwork for the further development of an autonomous control system has been laid, and the path forward is promising.

Der volle Inhalt der QuelleModeling a feed axis of a Computer Numerical Controlled (CNC) machine is a challenging problem due to its time-varying dynamics and parametric uncertainties. A simple but practical system identification method was proposed in this thesis and combined with the H∞ technique to design a robust controller for a high-precision CNC milling machine. The ballscrew driven worktable of a Southwestern Industries 2OP Mill was modeled by means of a standard frequency response test. The model was linearized around the first axial resonance, and then used to synthesize an H∞ controller based on the linear matrix inequality approach. The simulated closed-loop system was subjected to disturbances and to a reference tool path to test its disturbance rejection and command following capabilities. Another simulated closed-loop system based on the machine’s actual Proportional-Integral-Derivative (PID) controller was created and subjected to the same tests in order to compare the performance of the two controllers. In all simulations, the H∞ controller displayed better performance than the PID controller.

Der volle Inhalt der QuelleMånga applikationer har förbättras genom användningen av maskininlärning. Maskininlärning för reglersystem föreslogs redan på 1990-talet och har nu börjat tillämpas, eftersom processorkraft, lagringsmöjligheter och tillgänglighet till rådata ökat. I detta examensarbete användes ett inbäddat klimatsystem, som är en typ av reglersystem. Maskininlärningsmodellen Deep Belief Network användes för att undersöka hur delar av klimatsystemet skulle kunna återskapas. Först återskapades funktionaliteten hos en PID-regulator och sedan funktionaliteten av en mer komplex del av reglersystemet Prestandan hos nätverken utvärderades i jämförelse med prestandan i de ursprungliga kontrolldelarna och hårdvaran. Det visade sig att Deep Belief Network utmärkt kunde replikera PID-regulatorns beteende, medan prestandan var lägre för den komplexa delen av reglersystemet. Användningen av fördröjningar i indata till nätverken gav bättre resultat än utan. Ett klimatsystem med ett Deep Belief Network laddades också över på hårdvaran. Minimikrav för minnesanvändning och CPU- användning var uppfyllda, men CPU- användningen påverkades kraftigt. Detta gör, att om maskininlärning ska kunna användas i verkligheten, bör CPU-användningen minskas.

Der volle Inhalt der QuelleENGLISH ABSTRACT: This work considers the control of reconfigurable assembly systems using a welding assembly system as a case study. The assembly system consists of a pallet magazine, a feeding system, an inspection and removal system, a welding system and a conveyor. The aim of the work is to compare PC and PLC as controllers, as well as to compare two different approaches to reconfigurable control. The control system of the pallet magazine was developed using a PC and a PLC. The PC control was programmed using Visual C#, while the PLC was programmed in Ladder Logic using Siemens S-300 STEP7. The two controllers were compared based on the attributes that measure the quality of a controller's software, which include its capability, availability, usability and adaptability. The approaches to reconfigurable control considered were the agent-based methodology and the IEC 61499 distributed control methodology, both of which were applied to the feeding system. The agent-based control system was implemented using the JADE agent platform, while the IEC 61499 distributed control system was implemented using the FBDK software kit. These two methods were compared based on the characteristics of a reconfigurable system, which include the system's modularity, integrability, convertibility, diagnosability, customization and scalability. The result obtained in comparing the PC to the PLC shows that the PLC performs better in terms of capability, availability and usability, while the PC performs better in terms of adaptability. Also, the result of the comparison between the agent-based control system and the IEC 61499 distributed control system shows that the agent-based control system performs better in terms of integrability, diagnosability and scalability, while the IEC 61499 distributed control system performs better in terms of modularity and customization. They are, however, on a par in terms of convertibility.
AFRIKAANSE OPSOMMING: Hierdie werk beskou die beheer van herkonfigureerbare monteringstelsels met 'n sweismonteringstelsel as gevallestudie. Die monteringstelsel bestaan uit 'n paletmagasyn, 'n voerstelsel, 'n inspeksie-en- verwyderingstelsel, 'n sweisstelsel en 'n voerband. Die mikpunt van die werk is om persoonlike rekenaars (PCs) en programmeerbare-logikabeheerders (PLCs) as beheerders te vergelyk, asook om twee verskillende benaderings tot herkonfigureerbare beheer te vergelyk. Die beheerstelsel van die paletmagasyn is ontwikkel met 'n PC en 'n PLC. Die PC-beheer is in Visual C# geprogrammeer, terwyl die PLC in leerlogika met Siemens S-300 STEP7 geprogrammeer is. Die twee beheerders is vergelyk in terme van die eienskappe wat die kwaliteit van 'n beheerder se sagteware meet en sluit in vermoë, beskikbaarheid, bruikbaarheid en aanpasbaarheid. Die benaderings tot herkonfigureerbare beheer wat oorweeg is, is die agent-gebaseerde metodologie en die IEC 61499 verspreide-beheermetodologie. Beide is op die voerstelsel toegepas. Die agent-gebaseerde beheerstelsel is geïmplementeer met behulp van die JADE agent-platform, terwyl die IEC 61499 verspreide stelsel geïmplementeer is met behulp van die FBDK sagteware-stel. Hierdie twee metodes se vergelyking is gebaseer op die eienskappe van 'n herkonfigureerbare stelsel, waarby die stelsel se modulariteit, integreerbaarheid, diagnoseerbaarheid, pasmaakbaarheid en skaleerbaarheid ingesluit is. Die resultate wat in die vergelyking tussen die PC en PLC verkry is, toon dat die PLC beter vaar in terme van vermoë, beskikbaarheid en bruikbaarheid, terwyl die PC beter vaar in terme van aanpasbaarheid. Die resultaat van die vergelyking tussen die agent-gebaseerde beheerstelsel en die IEC 61499 verspreide beheerstelsel wys dat die agent-gebaseerde beheerstelsel beter vaar in terme van integreerbaarheid, diagnoseerbaarheid en skaleerbaarheid, terwyl die IEC 61499 verspreide beheerstelsel beter vaar in terme van modulariteit en pasmaakbaarheid. Hulle is egter vergelykbaar in terme van omskepbaarheid.

This thesis aims to design a data acquisition and dynamic monitoring and control system for high speed press machines. A PLC is used to control the actions of the machine and the states are transmitted to the database via the communication interface of the embedded human machine interface system. These data are then output to a terminal PC. We hope that the proposed system can shorten the mean time to repair. At the same time, the supervisor can know the operations of the machine and the situation of the productions. The monitoring and control system shows the failure status on the HMI. Therefore, the operator can easily execute the troubleshooting for the simple extraordinariness. It does not need the professional engineers to do the troubleshooting. Hence the cost and the mean time to repair can be effectively reduced. Furthermore, the system also shows the amount of the machining. When the amount reaching the setting quantity, the machine will stop automatically and send a finishing signal to the HMI. This method let the operators know to prepare the workpieces for the next machining, change the die and molds, or execute the parameter adjustment. By this monitoring approach, operator effort can be reduced. The payload and the cost of machines also can be decreased. Thus, this system improves the market competitiveness of companies.

The application of magnetic materials for hyperthermia of biological tissue has been studied for decades. The underlying notion of magnetic nanoparticle (MNP) thermotherapy is to utilize 10- to 50-nm diameter of ferric oxide (Fe3O4) which are heated up to 42 ℃ under AC magnetic field for cancer therapy applications. The size of nanoparticles and the strength and frequency of magnetic field all have influence to the heating efficiency of MNP. In order to achieve the goal of killing cancer cells using the AC magnetic field, we designed a digital controlled heating system to generate magnetic field that is frequency adjustable. The core of the system is based on a high speed microcontroller（TI TMS320F28235）and a full-bridge series resonant circuit for the high frequency induction heater. The heating results show that the system can produce fast and accurate outputs. The experiments show that the MNP produces thermal loss and has maximum temperature increase up to 13 ℃ under a AC magnetic field. Finally, we discuss the heating effect of different density of magnetic nanoparticles under different operating frequency.

It is becoming common practice to employ servo system in industrial machine control, which aims at increasing the reliability and productivity of products. As for the system cost, current products are not as expensive as those in the past, and they tend to be in the middle-low price bracket. As for functionality, general small and medium-sized axis motion control systems usually adopt PLC+Servo Drive configuration. This not only decreases the cost of developing equipment but also obviously increases the functionality. The proposed dedicated numerical control integrates local servo drive and CNC. Besides the mode of P command position servo-control signal, we also developed the mode of V command velocity servo-control signal, so that the system can run faster. The purpose of this study is to develop a CAM application software with dedicated graphical and user-friendly interface. This software realizes the function of converting DXF files into NC codes. Besides, the electronic circuit design of pressure and temperature sensor was also completed. Moreover, by integrating digital control system and our software into the same X-Y working panel, users can easily edit, design, and implement NC programs within the machine. This not only maximizes functionality of the machine, but also increases convenience of operation; at the same time, product value is also increased. After V command velocity servo-controller was developed, the dynamic contour error of controller was explored. It was found that the error resulted from simultaneous motor movement of all axes has interesting behavior. Besides, no matter what contour shape was defined, the controller can effectively suppress the geometric error between the command contour in the system and the practical tracking shapes.

The pneumatic counterweight system enables machine tools to support the weight of the spindle of the machine tool by using air cylinders. The pneumatic counterweight system is a suitable method of counterweight method because of its high speed and force capacity, combined with its low price and clean operations. The pneumatic pressure compensation method applied for the conventional pneumatic counterweight system is designed to connect a large air tank with a pneumatic cylinder. The air tank is connected to the compressed air source, the compressor, and the pressure regulator or the pressure switch is added to achieve the constant pressure. Therefore the pressure change in the pneumatic cylinder can be reduced due to the spindle motion. However, if the spindle of the machine tool travels at a faster rate, a constant pressure cannot be hold using the conventional method. Therefore this study reformed the pneumatic circuit of the conventional pneumatic counterweight system, the pressure regulator and pressure switch was connected to the cylinder directly. The variation of the pressure in the cylinder can be held by using the new pneumatic circuit. In order to increase the performance of the counterweight system and make the volume of the system smaller, the proportional pressure valve controlled circuit and servo valve controlled circuit are designed and developed as an alternative to the pneumatic counterweight system. The self tuning fuzzy controller was designed and implemented for regulating the pressure in the cylinder using the proportional valve. Through the control method, the fluctuation of the pressure can be decreased efficiently without connecting a large air tank if the machine tool travels at a faster rate. The performance of the proportional valve control system can be decreased at the higher speed and acceleration, so that a modified fuzzy sliding mode controller is developed to increase the stability of the pressure in the cylinder. Besides, the pressure of the cylinder can be also adjusted to eliminate the effect of the friction force by using servo valve controlled system. This control method can be reduced the load during machining and moving. The experimental results show that the proposed pneumatic control circuits and control methods have the ability, in practice, to improve the performance and stability of pneumatic counterweight system.
