摘　　要：永磁同步电动机在一定条件下或参数处于某特定区域会发生混沌现象,这影响了电动机运行的性能。根据微分几何理论,利用完全精确线性化的方法,设计出控制混沌的控制律。该方法以转子角速度为控制变量,通过电动机的非线性反馈进行解耦,转子角速度可以根据跟踪设定其稳定点。这个控制律可以使系统稳定在某一平衡点,而且这个平衡点不是唯一的,这样可以根据情况设定平衡点,满足了实际需要。实验仿真表明,利用完全精确线性化的可以使系统消除混沌,达到了新的平衡,这证实了控制律的有效性。Permanent magnet synchronous motor will happen chaos phenomenon in a particular parameters or in certain conditions . which is affect the performance of the motor running. Based on the theory of differential geometry, the completely accurate lineariza-tion method, the control law is designed to control the chaos. The method make the rotor angular velocity as a control variable, the motor is decoupled of the motor by the nonlinear feedback, the rotor angular velocity can set its stability according to the following points~ The control law can make the system stable in a certain balance, and the balance is not the only one, so we can set a balance according to the circumstance, which can meet the practical needs. Experimental simulation show that using the completely accurate linearization can make the system to eliminate chaos, and reached a new equilibrium, it confirmed the validity of the control law.
