| 摘 要： | 对于具有多变量、非线性、强耦合的无轴承永磁同步电动机悬浮与调速系统,实现电机两悬浮力分量之间以及悬浮力和电磁转矩之间的解耦控制是提高其系统性能的关键。建立了无轴承永磁同步电动机耦合的悬浮力模型,提出了一种前馈解耦方法,设计了前馈解耦控制器,将之串接于悬浮子系统中,实现了上述多变量之间的完全解耦,进行了控制系统的仿真研究。仿真结果证实了控制方案的可行性,控制系统具有优良的动、静态调节性能。

| Abstract: | For suspension and speed control system of bearingless permanent magnet synchronous motors(BPMSM),characterized by multi-variable,non-linearity and strong coupling,the key technique for improving its performance is to realize the decoupling control between the two force components,and between the forces and electromagnetic torque.A coupled suspension forces model of BPMSM was built,the feed-forward decoupling controller was designed and applied to the suspension subsystem,so the multi-variables were completely decoupled.The control system was verified with simulations.The simulation results show the validity of the control strategies,and the control system has fine dynamic and static performance. |
