摘要
在分析开关磁阻电机(SRM)数学模型的基础上,提出了SRM控制系统仿真建模的新方法。在Matlab/Simulink中,建立独立的功能模块,如电机本体模块、速度控制模块、电流控制模块、转角选择模块等,再进行功能模块的有机整合,搭建SRM控制系统的仿真模型。系统采用双闭环控制:速度环采用PI控制,电流环采用角位置控制与电流斩波控制相结合的方法,保证了SRM在低速或高速运行时都可获得满意的性能。仿真结果证明了该SRM建模方法的合理性、有效性,为实际电机控制系统的设计和调试提供了新的思路。
Based on the mathematical model of switched reluctance motor (SRM), a novel method for modeling and simulation of SRM control system based on Matlab has been proposed. In Simulink, the independent functional blocks, such as Moter model block, Speed controller block, Current controller block, Angle selection block, etc., have been modeled. By the organic combination of these blocks, the model of control system can be established easily. In the double loop of control system, a PI controller is adopted in the speed loop and a compound current controller is adopted in the current loop. In order to obtain expected performance, above base speed a speed angular position controller works in current closed-loop, and below base speed a current chopping controller works. The reasonability and validity have been testified by the simulation results and this novel method offers a new thoughtway for designing and debugging actual motors.
