摘　　要：研究了分数阶永磁同步电机混沌系统稳定控制问题。在不消除非线性项的情况下,设计了柔性变结构控制器,实现了分数阶永磁同步电机系统稳定控制。同时,基于分数阶系统Lyapunov稳定判定定理对系统状态的稳定进行了证明。柔性控制器在兼顾系统稳定性能与鲁棒性的同时,缩短了系统的调整时间。最后,利用所设计的柔性控制器实现了分数阶永磁同步电机混沌系统的稳定控制,仿真结果验证了所设计控制器的有效性和可行性。In this paper, the stability control problem of fractional-order permanent magnet synchronous motor chaotic system is investigated. A soft variable structure control scheme is introduced without eliminating the nonlinear part. At the same time, the stability of the systems is proved by the fractional order Mittag-Leffer theory. Giving consideration to the stability and the robustness of the system, the adjustment time is shortened. By using the designed controller, the stable fractional-order permanent magnet synchronous motor chaotic system is realized. The numerical simulation results verify the effectiveness and feasibility of the designed controller.
