PID_Controller_Matlab_Code

说明：  这个是信号与处理专业的大作业，主要研究两个方面的问题：低通滤波器的阶跃响应特性分析和连续线性系统的求解。通过这次课程设计，将会研究Matlab的一些基本的数值计算应用方法，对计算结果进行形象化地展示，有利于加深对本课程内容的理解。(This is a major task of signal and processing specialty. It mainly studies two aspects: step response characteristic analysis of low-pass filter and solution of continuous linear system. Through this course design, we will study some basic numerical calculation application methods of MATLAB, and visualize the calculation results, which is conducive to deepening the understanding of the course content.)

说明：  umat基础知识教学，适合刚接触UMAT的新手做参考(UMAT basic knowledge teaching, suitable for beginners)

说明：  该模型是对50kW、380V、50Hz三相三电平逆变器的两个相同电路进行建模。IGBT逆变器采用SPWM技术，(8kHz载频)将直流电源从a +/-200Vdc源转换为220V AC, 50Hz。逆变器通过75kVA 220/380V变压器输入50kW电阻负载。变频器输出采用L-C滤波器滤除主要产生于8kHz开关频率倍数(Fh=n*8000 +/-k*50Hz)附近的谐波频率Fh。逆变器所需的12个逆变脉冲由PWM发生器块产生。该系统以恒定的调制指标在开环中工作。 电路1使用三电平桥块对逆变器进行建模。电路2使用独立的IGBTs和二极管块。用开/关延时块模拟死区，仅在电路1上应用。(It is easy for us)
