电动汽车永磁同步电机优化控制方法的研究
Research on optimal control method for permanent-magnet synchronous motorin electric vehicle
摘要
Abstract
Since the traditional PID algorithm based driving method for permanent⁃magnet synchronous motor in electric ve⁃hicle has the problems of poor system response,weak stability,and slow steady⁃state speed recovery after suffering from load disturbance,a method of taking the integral sliding mode variable structure controller as the drive controller of the permanent⁃magnet synchronous motor of electric vehicle is proposed. The load torque observer introduced into the system can reflect the feedback value of the load torque in the current setting value,so the control system can respond to the load disturbance timely. The effectiveness of the studied method was verified with Matlab simulation. The research results show that the control method can observe the motor’s load effectively and accurately,make a response while load changing suddenly,and ensure that the ro⁃tate speed is controlled in the setting range rapidly.关键词
