开关磁阻电机非线性计算及动态系统仿真研究

Nonlinear Calculation and Dynamical System Simulation Studies for Switched Reluctance Motor Drive

基于ANSYS和Simulink对整个开关磁阻电机驱动系统建模、仿真,将有限元与控制结合对开关磁阻电机系统非线性特性进行仿真研究。通过对整个电机系统的研究建立一种快速、准确的非线性系统仿真环境,从而有助于对开关磁阻电机进行深一步研究、设计与控制。最后通过对样机低速运行情况下进行电流斩波控制仿真试验,验证结合有限元计算与控制系统仿真分析对开关磁阻电机非线性以及动静态特性研究的有效性。

ANSYS was connected with the control simulator Simulink to model and simulate switched reluctance motor drive. The target is to build a fast and accurate nonlinear system simulation environment which can be useful for future optimal studies, design and control strategy for switched reluctance motor. In the end, a simulation experiment was taken for a prototype motor under current chopped wave control （CCC） strategy at low speed, which validates the validity of connection between finite element method and control.
