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。

By comparison with the results of ideal Henon sequence mixed with noise,the improved Farmer algorithm is able to increase the precision of noise attenuation and reduce the absolute error between itself and ideal Henon sequ.

通过对混有噪声的Henon序列进行仿真实验，仿真结果显示，改进后的Farm er算法能够提高噪声衰减的精度，降低与理想Henon序列的绝对误差

Two errors have been defined in this dissertation, which is mean absolute percentage error (E2) and mean percentage error (E3). The application of the two errors has brought great convenience in building and application of RBFNN model.
