Abstract


Distributed Control System is not only based mainly on the microprocessor technique, but also the requirement of modern enterprise manufacture and the co-relationship among the control objects with the increasing complexity. From the view of process integrate automation, it can be regarded as one kinds of multi-level distributed computer control system, which has the concentrated way in dealing with information and management, while the scattered solution in control. It has been widely used in industrial production and the fields of control and management.Fault Tolerant Control is one kind new technique with the aim to enhance the system security and system reliability. FTC is basically depended on a great deal of online detection, parameter identification and model calculation. It can revise the system control rules when the fault occurred and then maintain the system operation according the original goal. And it has the specialty of stronger adaptability, higher reliability and better function etc.The paper regards the coal-transporting systen of the Huaneng Nantong power plant as the study object, applied the active tolerance to design the reconstructed model of tolerant control rule, to solve the two problems of real-time FDD and CRR.In the second chapter we divide the system to three independent parts according to the different function of the object, then towards one part of system, flow system, designed fault tolerant model using state space theory and matrix construction. In the third chapter it is applied the RBF neural network to solve the real-time FDD, and the simulation result is given by MatlabS. 3 software. In the fourth chapter the more details of realizing the fault tolerant flow control is discussed, and and the CRR is settled by the conclusion of FDD and the real-time function calculation which achieve the goal of the system control rule on-line reconstruction. In the fifth chapter we complied the simulated program by Visual C++ for the whole theory to draw the conclution. In the sixth chapter we applied the OPC technology to the actual object, then the tolerant program can be linked with the mainIIcoal-transporting program based on FIX software by a little modification. The way is associated with the development of high speed CPU so as to real-time compute some Gaussian function. It presents a way with tolerant idea for solving the security and reliability in DCS now.
