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.
