Delay System Intelligent Control Study

The big time delay phenomenon within the industry process is very widespread, its existence affected the stability of the system seriously, cause system overshot become big, adjust time to lengthen consumedly, even appear to flap and dissipation, the dynamic quality of the system becomes obviously bad. Since 50s appeared successively a lot of contro] methods the of big time delay process. But much of that methods base on the classic method or modern theories, its compute is huge complicate, so all of that methods are very difficult in the industry real application. Therefore, put forward simple, valid, processing a practical big time delay of control method is very meaningful, on the one hand the intelligence control method leads to go into and can further develop the classic method of the time deJay process control system, on the other hand, the function of these methods is stronger, ail of this provided the possibility implement them.Any thing in this world, it appears, it development is inevitable, it always along with produce needs. The development of the industry process caused the appearance of the complicated system, but the characteristics of the complicated system causes people to the research intelligence method. As a result, the development of the automat ic control methods at experienced the classic control theories and moderns control theories, further go into the intelligence control stage. The complicated system has the indetermination, nonlinear, time change and coupling characteristics, but the computer science and technology introduction bring the new motivation to develop intelligence methods, making a lot of method that un-applicant originally can become into real application.This text according to this stance, at, the aspect of big time delay system put forward following some control methods: On the foundation of the classic Smith, put forward more simple, more easy use the calculator , time-partition of pre-estimate and control method, and research it stability and robust. The nerve network control study hot currently, this text also research it, emphasizing to study the single nerve cell , to design of the PID intelligence controller, and to improvements that controller, and realize them and analyzed the single nerve cell stability.
