基于MATLAB/Simulink的开关磁阻电动机调速系统的建模与仿真

Modeling and Simulation of Switched Reluctance Drive Based on MATLAB/Simulink

介绍了开关磁阻电动机的准线性数学模型,使用MATLAB/Simulink建立了仿真模块库,其中包括电流计算、转子位移角计算、电磁转矩计算等模块,然后将这些模块有机结合搭建了开关磁阻电动机调速系统仿真模型,该模型低速阶段采用电流斩波控制方式,高速阶段采用角度位置控制方式。

Under MATLAB/Simulink environment , the simulation block library was firstly established, based on the approximate nonlinear mathematics model of switched reluctance motor（SRM） . This block library ineluded the current calculating block , the motor angle calculating block, the torque calculating block, etc. Then, by the combination of these blocks, a simulation model of switched reluctance driver （ SRD） was established easily, adopting Chopped Current Control （CCC） during lower speed and adopting Angular Position Control （ APC ） during higher speed.
