有关迫零均衡方面的研究，基于MATLAB平台的仿真，值得一看。(The study, based on zero-forcing equalizer MATLAB simulation platform, worth a visit.)

说明：  演变过程 自抗扰控制器自PID控制器演变过来，采取了PID误差反馈控制的核心理念。传统PID控制直接引取输出于参考输入做差作为控制信号，导致出现响应快速性与超调性的矛盾出现。(In the process of evolution, ADRC evolves from PID controller and adopts the core idea of PID error feedback control. Traditional PID control directly draws the output from the reference input as a control signal, which leads to the contradiction between response speed and overshoot.)

该程序仿真了基于三相逆变器的空间矢量PWM。可以在示波器上看到线电压，相电压和滤波电压。调制指数、DC电压和频率参数可以修改。(The program simulates the vector PWM space-based three-phase inverter. You can see the line voltage, phase voltage and filtering the voltage on an oscilloscope. Modulation index, DC voltage and frequency parameters can be modified.)
