The Computer Control System Of Compound Pipes Industrial Process

The study is a horizontal subject from Sanwei Company of Hebei Province, the title is the computer control system of compound pipes industrial process. It mainly is insist of IPC(industry process computer), intelligent regulator(IR),programmable logic controller(PLC), frequency-converter and alternating current motor. Now compound pipes industry belongs to high and new technology industry, there is not sophisticated technology and control strategy. But in order to guarantee production quality, better requirement on control is questioned. So in order to satisfaction of needs of production quality, this demands best control technology. Fuzzy control is a kind of method of personification, it is one of intelligent control showing thought of human beings, and people needn't know its accurate mathematical module. Because of intelligent control, its body is to simulate thoughts of human beings, and there is its shortage. Combine it to traditional PID controller will acquire better control result.The paper presents Self-regulation factor Fuzzy-PID controller and PID self-regulation fuzzy controller in order to control temperature lagging object and nonlinear object in taking-up device. First, we proceed MATLAB simulate study. Secondly, we use ActiveX controller supported by DELPHI language to realize them. In the end, we built the ActiveX controller in Kingview software, realizing control the controlled object, the result show the two control algorithms respond well.Now, the control system is used in Sanwei Company of Hebei Province, respond well, and require expected result.
