【Abstract】 A self-adaptive fuzzy PID controller,which has simpler structure and higher robustness,is built when fuzzy logic controller and PID controller are combined together appropriately.It can switch between fuzzy control and PID control according to the range of error automatically.The results of simulation show that the controller has improved dynamic and static performance of nonlinear control system and has obtained good control quality.更多还原
