说明：  感应双馈发电机系统的仿真,已经完美封装好,参数可自行更改(The simulation of the induction doubly fed generator system has been perfectly encapsulated, and the parameters can be changed by themselves)

建立MATLAB/ SIMULINK仿真，从基础学习，可以快速掌握控制系统的仿真(Establish MATLAB/simulink simulation, basic learning, can quickly master control system simulation)

模拟退化算法，用于解决TSP问题，有GUI(Analog degradation algorithm for solving TSP problem, there GUI)

HVDC Transmission System

基于无速度传感器的异步电机调速系统，运用电流来合成磁链，控制方法是转子磁链定向。采用电流滞环控制，电网电压380V，转矩最大达30N.m。波形效果不错。(Based on speed sensorless induction motor speed control system, using current flux synthesis method for controlling the rotor flux orientation. Use current hysteresis control, grid voltage 380V, maximum torque of 30N.m. Waveform good results.)
