摘　　要：提出一种不完全微分PID控制器组态,代替理想的PID控制器进行控制.对于系统外扰的影响,采用一种多环Smith预估器系统,利用MATLAB进行仿真.结果表明,该控制系统具有良好的抗外扰性能,可改善系统的调节品质.A kind of incomplete derivative PID controller is put forward to replace classic PID controller in a control system. A multi-loop Smith predictor is used to eliminate the influence brought about by the interrupt outside the system, and the effect of the predictor is simulated in the Matlab environment, the simulation results show that such a system characteristic of good resistance to the interrupt can improve the adjusting performance of the system.
