摘要: 通过Takagi-Sugen控制技术，建立了参数不确定永磁同步电机的Takagi-Sugen模糊控制模型，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的充分条件，最后通过实例证实了结果的正确性，相比传统的模糊控制方法，基于Takagi-Sugen模型的模糊控制方法具有一定的优越性.

Abstract: The permanent magnet synchronous motor （PMSMs） may have chaotic behaviors under certain working conditions, especially for uncertain values of parameters，which threatens its secure and stable operation. Hence，it is important to study methods of controlling or suppressing chaos in PMSMs. In this paper，the Takagi-Sugeno fuzzy control model for PMSMs with parameter uncertainties is established via the Takagi-Sugen modeling method. Based on the new model，the control conditions of asymptotical 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 curently available results，the obtained results exhibit some advantage.
