无轴承开关磁阻电动机模型分析与控制

在研究无轴承开关磁阻电动机的电机模型后,对影响它的六个悬浮力系数进行了仿真分析,在此基础上对这六个悬浮力系数合理简化,并针对径向两自由度的解耦提出三种参数的控制器。采用反馈线性化方法进行了动态解耦,最后分别采用三种参数的控制器在Matlab环境下进行了整个径向位置控制系统的仿真建模。仿真结果显示,控制器采用两个参数时就可达到比较好的解耦效果。

Model Analysis and Control of Bearingless Switched Reluctance Motor

Based on the discussion of the bearingless switched reluctance motor model,six levitation coefficients that influence the model were analyzed and simulated.Then reasonal simplification was done to the six coefficients,and a controller with three parameters was proposed to deal with the radial two-degree decoupling.Feedback linearization method was adopted to perform dynamic deconpling.Finally,simulation model of the whole radial position control system was set up in Matlab by employing three parameter contr...
