中文说明：pwm整流器的建模仿真，有较好的参考价值，有PMUSIC 校正前和校正后的比较，多目标跟踪的粒子滤波器，随机调制信号下的模拟ppm，仿真效率很高的。
English Description：
PWM rectifier modeling and simulation, there is a good reference value, there is a comparison of PMUSIC before and after correction, multi target tracking of the particle filter, random modulation signal simulation ppm, simulation efficiency is very high.
