Two optimal filter are recommed to filter of IMC system,One,is ITAE filter that comform to the minimum integral of time-multiplied absolute error,i,e,J=∫｜e｜tdt→min,Other is Butterworth filter that have a good character of idea low-pass filter.

推荐两种滤波器作为IMC系统的滤波器。一种是ITAE滤波器，它符合时间乘绝对误差积分值最小的优化原则，即J =∫|e|tdt→min ；另一种是Butterworth滤波器，它具有很好的理想低通滤波器特性。
