摘　　要：应用零极点相消法设计内模控制器，选取内模控制器的滤波系数，以满足预定不确定性下鲁棒性的要求。用PID规律逼近IMC控制来确定PID参数。仿真结果表明，所设计的控制器具有较好的动态性能和鲁棒稳定性，适用于大型工业过程。The paper introduces the internal model controller is designed through Pole-zero Cancellation in order to make its filter coefficients meet robust demands when the conditions are not confirmed. And PID parameters can be determined with PID law to approach IMC. The emulated results have showed that the controller designed has better dynamic capability and robust stability, applicable to the large industrial process.
