中文说明：具有丰富的参数选项,最小均方误差（MMSE）的算法，采用偏最小二乘法，IMC-PID是利用内模控制原理来对PID参数进行计算，基于kaiser窗的双谱线插值FFT谐波分析，可以得到很精确的幅值、频率、相位估计。
English Description：
Has a wealth of options, minimum mean square error (MMSE) algorithm, using partial least squares method, IMC-PID is by using the internal model control principle of PID parameters are calculated, based on the Kaiser window double spectrum line interpolation FFT harmonic analysis can be very accurate amplitude, frequency and phase estimation.
