中文说明：IMC-PID是利用内模控制原理来对PID参数进行计算，最小均方误差（MMSE）的算法，真的是一个好程序，包括回归分析和概率统计，包括单边带、双边带、载波抑制及四倍频,对于初学者具有参考意义。
English Description：
IMC-PID is the PID parameters by using internal model control theory to calculate the minimum mean square error (MMSE) algorithm is a really good program, including regression analysis, and probability and statistics, including unilateral, bilateral, carrier suppression and four times times the frequency, are useful for beginners.
