Intelligent Application Of The Pid Algorithm And Hybrid Control System Design

In this paper, a high performance servo system which is applied to the small caliber gun was studied. In order to get the high performance: high speed, high acceleration, and can track the set-signal quick, we use the intelligent PID to control the system. How intelligent PID is designed in the project, what is its result and performance using this control also is introduced and analyzed, the high performance requirement was satisfied. In next paper, what is hybrid system, why hybrid system should be used, and the hybrid system's model structure, hybrid system's mathematical models and hybrid control system design also are introduced. Intelligent PID can be regarded as a hybrid control. Then the hybrid model, Lyapunov theorem for hybrid control systems are studied and two methods of designing hybrid control which make sure the hybrid control system stable are also introduced. Furthermore, an ideal how to using the designing method of hybrid control to design the intelligent PID is given, As for the searching of the Lyapunov function, it can be formulated as LMIs. The simulations also are done, the result show the validity of the method.
