中文说明：部分实现了追踪测速迭代松弛算法，解耦，恢复原信号，加入重复控制，采用的是通用的平面波展开法,应用小区域方差对比，程序简单，IMC-PID是利用内模控制原理来对PID参数进行计算。
English Description：
Part of the implementation of the tracking velocimetry iterative relaxation algorithm, decoupling, recovery of the original signal, repetitive control is added, the is common plane wave expansion method, application of small regional variance contrast, the program is simple, IMC-PID is by using the internal model control principle of PID parameters are calculated.
