说明：  基于窗函数的FIR滤波器设计，窗函数可以采用多种，本次使用的是矩形窗。(FIR filter design based on window function, window function can be used a variety of, the use of rectangular window.)

用LAPLACE方法求解多维沃尔泰拉方程，此处为一个变元的方程，由于该方程同时含有微分和积分，一般求解有一定的困难。此处为MATLAB程序，注意不同的初始条件-used method for multiple preoperational Ertaila equation here as a variable element of the equation, As the same time contain differential equations and integral, the general solution is definitely difficult. MATLAB here for the procedure to different initial conditions

基于重复补偿控制，将重复补偿与PID结合，达到更好的位置跟踪，仿真对象为一个简化的PMSM模型。 重复补偿PID控制与传统PID控制相比较，稳态误差更小，可看仿真效果图。 这算法可用在精密伺服控制中。
