Robust control based on L_2-gain for servo system of switched reluctant motor

通过对开关磁阻电机非线性特性分析,提出了开关磁阻电机(SRM)伺服系统L2鲁棒控制器设计方法。建立速度误差动态方程,结合L2鲁棒控制器理论,通过L2控制器的设计解决了SRM的负载扰动和转速跟踪问题。设计存储函数证明L2控制器实现了扰动抑制和渐进稳定。仿真结果表明,该控制器能够保证系统达到很好的扰动抑制和转速跟踪效果。

A design of L2 robust controller for the servo system of SRM（Switched Reluctant Motor） is proposed based on its nonlinear characteristic analysis. The dynamic equation of speed error is built and,combined with the L2 robust controller theory,the load disturbance and speed tracking of SRM are involved in the design of L2 controller. The storage function is designed to prove that the L2 controller realizes the disturbance suppression and asymptotical stability. Simulative result shows that the designed controller restrains the disturbance and tracks the speed effectively.
