摘要
介绍了开关磁阻电动机的准线性数学模型,以此为基础,使用Matlab/Simulink建立了通用的开关磁阻电机仿真模型;设计了电压斩波控制,电流斩波控制,换相控制等开关磁阻电机控制器的通用模块,从而建立了开关磁阻驱动系统仿真模块库。研究重点是设计基于皮特里网络(Petri-Net)的SRD控制策略选择器,并提出适用于微控制器实时控制的皮特里网络算法,仿真和实验结果都表明对优化SRD的四象限运行控制有较明显的效果,可应用于实际。
A universal SRM simulation model is proposed based on the approximate nonlinear mathematical model. The SRD simulation block library including the SRM model, the voltage-chopping block, the current-chopping block and the commutation-control block is created for further research. The emphasis of the research is the design of SRD strategy selector using Petri-Net. A novel Petri-Net algorithm, which is suitable for real-time control with micro-controller, is also proposed. This strategy selector is proved to be effective in optimizing the SRD four-quadrant running performance.
