摘　　要：针对永磁同步电动机混沌系统，考虑受不确定因素的影响，对其数学模型采用基于微分几何理论的精确反馈线性化法，建立鲁棒控制模型，设计鲁棒控制器，实现永磁同步电动机混沌系统的鲁棒镇定和输出跟踪控制。数值仿真的结果证明了所提出方法的有效性及控制器的鲁棒性。In this paper, targeting the permanent magnet synchronous motor chaotic system, we consider the system influenced by uncertain factors. We use the method of the exact feedback linearization which is based on differential geometry theory to establish the nonlinear robust control model and design the robust controller for realizing the robust stabilization and output tracking control of the permanent magnet synchronous motor chaotic system. Numerical simulation results demonstrate the effectiveness of the proposed method and the robustness of the controller.
