摘　　要：为解决永磁直流无刷电机转矩脉动大造成的作动器能耗高的问题,研究一种新型三闭环控制算法,外环采用电机转角PI控制,中间环采用转速PI控制,内环采用定子电流最优控制.基于Simulink建立14自由度整车模型和电机式主动稳定杆及其控制系统的仿真模型,仿真结果表明,控制算法能有效改善车辆的侧倾稳定性及乘坐舒适性,同时电机输出特性得到改善,系统能耗降低.In order to solve the problem of high energy consumption of the electric active stabilizer bar caused by the large torque ripple of the permanent magnet brushless DC motor,a new control algorithm was proposed for three-closed loops.In the outer loop,the PI controller was arranged for motor running angle control.In the middle loop,the PI controller was for the rotate speed control.The optimal control algorithm was used in the inner loop for the stator current control.Based on Simulink softer,14 DOF vehicle model,electric active stabilizer bar system and its controller model were established and simulated.The simulation results show that the new algorithm can effectively improve the roll stability and ride comfort of vehicle and output performance of motor.The energy consumption of the system is also reduced.
