Abstract:
The method of transforming a ladder diagram (LD) and an instruction list (IL) of PLC (Programmable Logic Controller) to each other is investigated in this paper. Firstly, ladder-step is adopted on transforming LD into IL. Ladder-step is divided series or parallel by using recursive algorithm, and then complicated ladder-step can be divided into several simple ladder-steps which can be converted to IL easily. When obtaining simple ladder-steps’ IL, combining them together to get final IL program of complicated LD program. Secondly, on transforming IL into LD, stack algorithm contributes a lot. Scanning IL to generate LD of each instruction block, and then pushing them into stack. Combine LDs in the stack by operating instruction, and then IL is transformed into LD successfully. Finally, in the last part of this paper, we show our PLC software and lower position machine. In addition, this transforming algorithm has already applied in PLC software successfully.

Abstract:
The last decade has witnessed rapid developments in computer technology, which in return, has found widespread applications in manufacturing systems, communication networks, robots etc. Such systems are called Discrete Event Systems (DESs), in which properties such as non-determinism, conflict and parallelism are exhibited. As DESs become more complex, the need for an effective design tool and its implementation becomes more important. Supervisory control theory, based on finite state machines (FSM) and formal languages, is a well established framework for the study of DESs. In supervisory control, given a model of the system and the desired system behaviour specifications, the objective is to find a supervisor (controller) such that the controlled behaviour of the system does not contradict the specifications given and does not unnecessarily constrain the behaviour of the system. In general, the classes of specifications that have been considered within the supervisory control fall into two categories: the forbidden state problem, in which the control specifications are expressed as forbidden conditions that must be avoided, and the desired string problem, in which the control specifications are expressed as sequence of activities that must be provided. In supervisory control, there are some problems when using FSMs as an underlying modelling tool. Firstly, the number of states grows exponentially as the system becomes bigger. Secondly, FMSs lack from graphical visivalisation. To overcome these problems Petri nets have been considered as an alternative modelling tool for the analysis, design and implementation of such DESs, because of their easily understood graphical representation in addition to their well formed mathematical formalism. The thesis investigates the use of Petri nets in supervisory control. Both the forbidden state problem and the desired string problem are solved. In other words, this work presents systematic approaches to the synthesis of Petri-nets-based supervisors (controllers) for both the forbidden state problem and the desired string problem and introduces the details of supervisory design procedures. The supervisors obtained are the form of a net structure as oppose to supervisors given as a feedback fiinction. This means that a controlled model of the system can be constructed and analysed using the techniques regarding to Petri net models. In particular the thesis considers discrete manufacturing systems. The results obtained can be applied to high level control of manufacturing systems, where the role of the supervisor is to coordinate the control of machines, robots, etc. and to low-level control of manufacturing systems, where the role of the supervisor is to arrange low-level interactions between the control devices, such as motors, actuators, etc. An approach to the conversion from the supervisors to ladder logic diagrams (LLDs) for implementation on a programmable logic controller (PLC) is proposed. A discrete manufacturing system example is then considered. The aim of this is to illustrate the applicability, strengths and drawbacks of the design techniques proposed.

Abstract:
An important consideration in discrete event dynamic systems control theory is the selection of a suitable modeling formalism that can capture the complex characteristics of the system and the capability to automatically synthesize a controller based on the system model. Net condition event systems are well suited for modeling complex discrete event dynamic systems owing to their input and output structure, which effectively captures the behavior of the physical devices to be monitored and/or controlled. To date, net condition event systems control models have not been extensively applied to highly automated manufacturing systems and there are few guidelines on how to automatically generate Programmable Logic Controller programming languages from net condition event systems models. This research automatically converted net condition event systems control models into Programmable Logic Controller programming language and evaluated the applicability of the proposed methodology in highly automated manufacturing systems using HAS-200 as a test bed.

In a production system, efficiency, speed and flexibility are important means for cost reductions. The complexity of automation systems has been increasing, which makes necessary the implementation of more efficient control programs, free of errors and easy to maintain. However, in most practical applications the solution of these problems is dependent on designer's experience and doesn t follow a formal methodology, which results in programs with errors and difficulties to understand and maintain, since only the designer understands the adopted solutions. The Supervisory Control Theory (SCT) is a method extensively researched in academic circles for the synthesis of control logic of automated systems. It allows control problems to be solved in a formal way, ensuring a minimally restrictive and no blocking solution that meets the control specifications. However, this theory is not widely used in industrial environments yet, once the methods for implementation of supervisors obtained by TCS are still deficient. Thus, the intention of this Dissertation consists of showing a methodology for implementation of supervisory control in Programmable Logic Controllers (PLCs). In this work, the synthesis of supervisors is made in accordance to local modular approach, which brings the benefits of a formal methodology and allows exploring the modularity of the plant and the control specifications. The implementation is based on an architecture structured in three levels: supervisor, interface and system to be controlled. For the implementation in CLP three different programming languages are applied: the high-level languages Sequential Function Charts (SFC) and Structured Text and the low-level Ladder Diagram language in some parts. The development of the methodology was based on two works: a doctoral thesis by Vieira (2007) and master thesis by Cruz (2011) and brought together the advantages presented in each one of these. To compare the proposed methodology and the two mentioned methods, several tests were made on a manufacturing cell available at PUCPR and simulations on a PLC and computer as well. The results show that the use of the methodology proposed in this work makes possible to implement PLC programs that are able to treat all non-controllable events occurred in the system to be controlled and treat one controllable event by each control cell in the same scan cycle. Furthermore, the use of high-level languages results in a program of easier interpretation and maintenance, also enabling reutilization of codes. In this work some problems related to CLPs implementations are also showed and proposals for solving them are presented, as properties as well that, if accepted, ensure that the problem does not occur.<br>Hoje em dia a competitividade entre as empresas está cada vez maior. Em um sistema de produção, a eficácia, a velocidade e a flexibilidade são importantes, pois significam redução de custos. Os sistemas de automação atuais estão cada vez mais complexos, justificando a necessidade de programas de controle mais eficientes, sem erros e de fácil manutenção. Entretanto, na maioria das aplicações práticas a solução destes problemas é feita com base na experiência do projetista, não seguindo uma metodologia formal, o que resulta em programas com erros e de difícil entendimento e manutenção, uma vez que só o projetista entende perfeitamente as soluções adotadas. A Teoria de Controle Supervisório (TCS) é um método para a síntese da lógica de controle de sistemas automatizados. Ela permite que problemas de controle sejam solucionados de modo formal, garantindo uma solução minimamente restritiva e não bloqueante e que atenda às especificações de controle. Entretanto, esta teoria ainda não é amplamente adotada em ambientes industriais, sendo a carência de métodos de implementação dos supervisores obtidos via TCS um elemento que contribui para que isso aconteça. Assim, esta dissertação se propõe a apresentar uma metodologia de implementação de controle supervisório em Controladores Lógicos Programáveis (CLPs). Neste trabalho, a síntese de supervisores é feita de acordo com a abordagem modular local, que traz os benefícios de uma metodologia formal e ainda permite explorar a modularidade da planta e das especificações de controle. A implementação é baseada numa arquitetura estruturada em três níveis: supervisor, interface e sistema a ser controlado. Para a implementação em CLP são empregadas três linguagens distintas de programação, as linguagens de alto nível Sequential Function Charts (SFC) e Structured Text, bem como a linguagem Ladder Diagram em algumas partes. O desenvolvimento da metodologia foi baseado em dois trabalhos: a tese de doutorado de Vieira (2007) e a dissertação de mestrado de Cruz (2011) e permitiu reunir as vantagens apresentadas em cada um destes. Para comparação entre a metodologia proposta e as duas metodologias citadas, foram feitos diversos testes em uma célula de manufatura existente na PUCPR, bem como simulações em CLP e em computador. Os resultados mostram que a metodologia proposta neste trabalho permite a implementação de programas em CLP que, num mesmo ciclo de varredura, são capazes de tratar todos os eventos não controláveis ocorridos na planta e ainda um evento controlável por célula de controle. Além disso, o uso de linguagens de alto nível resulta em um programa de mais fácil interpretação e manutenção, possibilitando ainda o reaproveitamento de códigos. Nesta dissertação também são abordados alguns problemas de implementação da estrutura de controle supervisório em CLPs, apresentando-se propostas para solucioná-los, bem como propriedades que, se atendidas, garantem que o problema não ocorra.

Abstract:
碩士<br>國立彰化師範大學<br>電子工程學系<br>107<br>The extending of functionary PLC in industry control systems has been frequently prevented by manufacturer brand and monopoly. The main function of the industrial logic controller is to receive a series of sensing events of the controlled system, and generates control action feedback to the controlled system via the specific control logic operation program to achieve the designated process goals. The dynamic reconfigurable capabilities of FPGA are ideally suited to the way in which PLC frequently adjust application system architectures. Therefore, in the development of the variety industrial control system, the realization of PLC with FPGA components can improve the system's programmability and customization. On the other hand, the operational type of the data stream should be the most natural type of industrial logic controller. At present, FPGA are often used in the implementation of hard-wired functional modules to improve the operational efficiency to approach the operating speed of hardware gates. In this thesis, a software tool of PLC ladder diagram to VHDL translator is developed to translate the input control program represented by the PLC ladder diagram into the corresponding VHDL hardware description language program file. The realization of the entire translation software tool uses Python as the main language, and uses VHDL as the medium language accompanying to FPGA customized synthesis tool to generate the serial stream code, and then downloads to FPGA chip to complete the PLC programming process. The control logic is configured as a hard-wired logic circuit through the translation software tool, and the data stream operation mode in configured FPGA can quickly respond to various sensing events to achieve various control targets in real time. In addition, FPGA synthesizer also provides hardware simulation tools for simulation, functional verification, and debugging of PLC programs. Translating the PLC ladder diagram into VHDL and hard-wired it into FPGA chip, the execution speed of FPGA can be thousands of times higher than the traditional PLC, which strengthens the value and importance of the FPGA in industrial control applications.

Abstract:
AbstractIn order to break through the traditional von Neumann architecture of computing and memory cell separation and speed up the computing speed, it is necessary to realize in memory computing, and memristor is an excellent carrier to realize in memory computing. Then, the development, principle, characteristics and application prospect of memristor are briefly introduced, and the characteristic curve of memristor is obtained by simulating the model of memristor. The principle and characteristics of memristor are explained more intuitively. Then, based on the memory resistor, the simple logic circuit design principle is described. The logic structure can be realized by using the memory resistor as the calculation element and adding a CMOS inverter, so as to realize the simple logic circuit. The paper designs the simple logic circuit including gate, gate, or gate by spice software, and simulates the circuit of gate, gate, gate, or gate. Then, based on the above logic gate, the circuit design of adder is carried out, the circuit diagram and design scheme are given, and the simple description and SPICE simulation are given. The design scheme is reviewed and summarized, its advantages and disadvantages are analyzed, and the optimization and improvement scheme is proposed.

Abstract:
AbstractWe present a method for automatically building diagrams for olympiad-level geometry problems and implement our approach in a new open-source software tool, the Geometry Model Builder (GMB). Central to our method is a new domain-specific language, the Geometry Model-Building Language (GMBL), for specifying geometry problems along with additional metadata useful for building diagrams. A GMBL program specifies (1) how to parameterize geometric objects (or sets of geometric objects) and initialize these parameterized quantities, (2) which quantities to compute directly from other quantities, and (3) additional constraints to accumulate into a (differentiable) loss function. A GMBL program induces a (usually) tractable numerical optimization problem whose solutions correspond to diagrams of the original problem statement, and that we can solve reliably using gradient descent. Of the 39 geometry problems since 2000 appearing in the International Mathematical Olympiad, 36 can be expressed in our logic and our system can produce diagrams for 94% of them on average. To the best of our knowledge, our method is the first in automated geometry diagram construction to generate models for such complex problems.

Abstract:
Control Systems are used to produce a certain result with little or no human supervision. The principal aim of such systems is to ensure that resources are used efficiently and that the desired product quality is achieved. Moreover for critical systems such as oil and gas plants, it is important to guarantee the safety and dependability of the operation. Therefore, it is necessary to verify whether what is running in the device is in accordance with what was defined in the specification documents. The goal of this chapter is to present a method that automatically generates the timed automata models from the specification ISA 5.2 Binary Logic Diagrams, and the implementation Ladder programs, for model-based analysis, in order to increase the confidence in the behavior of critical Control Systems. This approach is based on the use of the Uppaal tool and the Uppaal-TRON testing tool.

Abstract:
Abstract The manufacturing industry is relying more and more on artificial intelligence (AI). Despite this, Programmable Logic Controllers (PLCs), one of the most common industrial tools, still lack AI integration. This means that PLCs are still very rigid and struggle with handling uncertainties. Uncertainties are input data that the controller has not been programmed to address. Uncertainties can be caused by variation in sensor data or other factors. Because PLCs struggle to handle uncertainties, this makes them very tedious to program. Implementing AI into the PLC may eliminate this problem. This study answers the question of whether AI can be implemented into a PLC (Allen-Bradley). To do this, a Levenberg-Marquardt backpropagation artificial neural network (ANN) was trained in MATLAB to approximate a mathematical function. A representation of the ANN was then constructed using the PLC ladder logic diagram by implementing the weight and bias values obtained from the trained ANN. The PLC-implemented ANN’s results were validated by comparing its output values to those of MATLAB trained ANN. Negligible differences between the outputs indicate that implementing an ANN framework into the PLC ladder logic code is viable. The ability to implement an ANN into the PLC code may help PLCs handle uncertainties better. This implementation may help the PLC become more versatile for more jobs and may also make it easier to program. Future studies should test out this method of implementation and apply it in real world applications.
