Based on model reference adaptive control principle,a new adaptive PID controller was dis- cussed.A simple self- tuning method of PID control parameters was proposed by introducing an adaptive error signal.Compared with the typical PID controller,the new adaptive PID controller improves the dy- namic performance of the system greatly,and can track the model reference output well.The simulation results show that the new controller notonly ensures the desired closed- loop system behavior,butalso re- duces the mutual channels influence in multivarible systems.It has high robustness to external distur- bances.
