参数不确定永磁同步电机混沌的模糊脉冲控制

Fuzzy impulsive control of chaos in permanent magnet synchronous motors with parameter uncertainties

通过Takagi-Sugen控制技术和脉冲控制技术,建立了参数不确定永磁同步电机的Takagi-Sugen模糊脉冲控制模型,然后利用矩阵分析和Lyapunov稳定性理论,得到了参数不确定永磁同步电机渐进稳定和指数稳定的充分条件,最后通过实例证实了该结果的正确性,相比传统的控制方法,基于Takagi-Sugen模型的模糊脉冲控制方法具有一定的优越性.

In this paper, the Takagi-Sugeno（T-S） fuzzy impulsive control model for PMSMs with parameter uncertainties is established via the T-S modeling technique and impulsive technique. Based on the new model, the control conditions of asymptotical and exponential stability for PMSMs with parameter uncertainties have been derived by Lyapunov method and matrix analysis. An illustrative example is also given to show the effectiveness of our results. Compared with the existing results, the obtained results exhibit certain advantage.
