摘　　要：电机是电动汽车驱动系统的核心,无刷直流电机(BLDC)在运行过程中会产生非线性混沌运动,影响车辆的寿命以及给行车安全带来不利的因素。从基本的d-q轴无刷直流电机模型出发,建立一个只含有两个参数的无纲量混沌模型,分析混沌现象的产生机理。根据BLDC的d-q混沌模型,把其中的交、直轴电压作为系统的控制量,采用参数自适应延时反馈法来对BLDC混沌现象进行抑制或消除。理论分析与数值仿真表明,控制器的设计具有科学性,能有效抑制混沌。Motor is the core of electric vehicle propulsion system, and nonlinear chaotic motion is appeared in the work- ing condition of brushless DC motor, which will bring bad influence on the life of vehicle and the safety of driving adverse fac- tors. In this paper, from the basic d-q axis brushless DC motor model, a chaotic model containing only non-dimensioral parameters is astablished, and the generating mechanism of chaotic phenomena is analysed. According to the d-q chaotic model, the direct-axis and quadrature-axis voltage is used as manipulated variable, and the adaptive parameters delay feed- back is used to restrain or eliminate BLDC chaos phenomenon of motors. Theoretical analysis and numerical simulation show that the design of controller is scientific and can effectively restrain the chaos.
