Optimization Design of PID Controller and its Application

PID control has been largely applied in the industry process control because of its robustness and easy realization, But it is very difficult to tune the three parameters of PID controller, which often leads to oscillation and overshoot of the controlled object. Due to no repetition and random of chaos dynamics, a method to search for PID controller parameters based on chaos variable is proposed according to the performance index of control system. and then by which practicality pendulum is controlled. Experiment results show that the method is efficient to realize self-tuning parameters of PID controller, provides an effective way for optimization design of PID controller.
