Texto completoNetworked Control Systems is a control system where the plant and the controller exchange information via a shared communication network and the network is considered as part of the closed loop control system. Unfortunately the network introduces network induced random varying time delays and data packet loss amongst the communication network imperfections. The network delays are considered to be between the controller and the actuator and between the sensor and the controller. These network imperfections degrade the performance of the closed loop control system and result in closed loop system instability. The complexity of measuring the communication network imperfection in networked control systems makes it difficult for the control engineers to develop methods for design of controllers that can incorporate and compensate these imperfections in order to improve the performance of the networked control systems. In this thesis a co-simulation toolset called LabNS2 is developed to address the first problem of measuring the communication network imperfections by providing an ideal environment that can be used to investigate the influence of network time delays or packet loss. The software environment of the toolset is based on LabVIEWTM and Network Simulator Version 2 (NS2). A new robust predictive optimal controller design method is developed to address the problem of the destabilising effect of the network induced time delay between the controller and the actuator. The design approach is based on time shifting of the optimisation horizon and a state predictor. The design of the controller is based on a model of the plant with delay in the control vector equal to the delay between the controller and the actuator or to the sum of the delays between the controller and the actuator and between the sensor and the controller. The time shifting approach allows the design of the controller to be performed for a model without time delay. Then the control action is based on the future values of the state space vector estimates. The state predictor is developed to predict these future values of the state using the present and past values of the state estimates and control actions. This technique is made possible by the use of the plant model Transition Matrix. A Discrete Kalman Filter is modified to address the problem of the destabilising effect of the network induced time delay between the sensor and the controller. An additional state estimation vector is added to the filter estimate at every current moment of time. iv The developed methods are implemented for networked control of a dish antenna driven by two stepper motors. The outcomes of the thesis can be used for the education and fundamental research purposes, but the developed control strategies have significant sense towards the Square Kilometer Array projects and satellite systems industry.

The proposal for this study is to obtain an adaptive controller by feedback states for fourth order time-varyng multivariable systems or with parametric uncertainty. Alternatively the difficulties and limitations involving the usual methods of synthesis of optimal controllers for this class of systems, through the investigation of an algorithm based on particles swarm optimization with good tuning of parameters, we seek to define a flexible structure for applications that require decision making and online estimation of the feedback matrix parameters. The controller developed should provide, for every execution, not only system stability, but at the same time, provides compliance to the performance indexes set, without the need to perform complex and expensive mathematical calculations, eliminating thus the subjective components of analysis and design
É proposta neste trabalho a obtenção de um controlador adaptativo por realimentação de estados para sistemas multivariáveis de quarta ordem variantes no tempo e com incertezas paramétricas. Em alternativa às dificuldades e limitações envolvendo os métodos usuais de síntese de controladores ótimos para esta classe de sistemas, por meio da investigação de um algoritmo baseado na otimização por enxame de partículas com boa sintonia dos parâmetros, busca-se a definição de uma estrutura flexível destinada a aplicações que demandem a tomada de decisão e estimação em tempo real dos parâmetros da matriz de realimentação. O controlador desenvolvido deverá fornecer, a cada execução, não somente estabilidade ao sistema, mas ao mesmo tempo, propiciar observância aos índices de desempenho fixados, sem a necessidade da realização de cálculos matemáticos complexos e dispendiosos, eliminando, dessa forma, as componentes subjetivas de análise e projeto

In manufacturing industrial, for example, petrochemical plant, the promotion of technology makes manufacturing process computerization to be possible. The systems which control the manufacturing process are called Process Control System. Enterprises introduce the projects of process improvement to reduce the operation cost and enhance the product quality. It is necessary to have comprehensive information and technology to support the success of project for process improvement. Thus, it is a trend to setup the connections among Process Control Network, Process Information Network and Intranet. Due to the connections among networks, Process Control System is facing the threats of computer viruses, worms, attackers, and other malicious codes. Process Control System controls the manufacturing process base on the instructions issued from operators to maintain plant operations in a safe condition. Process Control System is the kernel of process operations. If Process Control System is being attacked or infected by computer viruses, the impacts would be the disclosure of critical business information, the failure of servers/workstations for monitoring process, or Process Control System fails totally that result in the plant operations with risky. The worst case would be an incident about pollution of environment, explosion, properties destroyed, or life lost. Therefore, enterprise should focus on reinforcing the information security mechanism of Process Control System to ensure plant operations reliably and safely. The objectives of this study are: a) To realize the challenges and threats that Process Control System is facing by the way of literature review. b) To discuss information security management related issues and resolutions of Process Control System base on physical, network, and servers respectively. c) To discuss the efficiency of the model of information security management that has been implemented in the enterprise. d) To make this study as a reference for related industries.

Polishing is the grinding technique which can produce the ultra-precision smooth mirror surface. The technique, directly or indirectly, is on behalf of a national machinery manufacturing standards. Belonging back end of line (BEOL) processing optical element production, polishing plays an important role in improving performance not only the quality of life but development of high-tech products. The domestic polishing technique for spherical lens has reached certain level, but spherical lens still have some problem like chromatic aberration and distortion. To solve this kinds of problem, aspherical lens, which cannot be manufacture by traditional polishing technique and can only be fabricate by computer-aided polishing, are used to improve image quality and decrease optical system volume. Computer-aided polishing is studied in this paper. Focusing on surface texture, association between polishing parameters and surface quality are discussed by material removal experiments. For computer-aided polishing fabrication, surface feed rates of polishing bonnet are not the crucial factor of surface texture. And, mid-spatial frequency error can be effectively eliminated by replacing one-direction path by multiple-direction paths. Values of surface’s peak-to-valley and root-mean-square can also be reduced. The cost of polishing process can also be declined at the same time. Hope that this research can promote the development of high accuracy polishing technique and domestic polishing apparatus.
