Optimization of PID Control Scheme Based on Eclectic Principle

Based on the satisfactory solution principle(SSP), this paper analyzes the contradictory relation and studies the approximate relation of PID control system. Through the approximate relation, the eclectic principle applied in the optimization of PID control scheme is decided. An example is proposed to testify the correctness and rationality of the optimization of PID control scheme based on eclectic principle. Some characters and applicable range of this optimize means are also discussed.
