摘要
对永磁同步电机的稳定性能进行控制,能够有效稳定汽车动力系统运行状态。对永磁同步电机稳定性的控制,需要获取电机相位补偿阈值,对电机位置进行估算,完成电机稳定性的控制。传统方法先给出角频率特性,计算磁链与感应电动势时域关系,但忽略了估算电机位置,导致控制精度低。提出基于速度环模糊的永磁同步电机稳定性能控制方法。组建解模糊表格,记录电机转动频率最大模糊次数,设计电机状态观测器,对电机微分值调节增益律进行表述,估计转子位置坐标,组建电流状态方程,得到电流微分差值,考虑转子角误差获取电机相位补偿阈值,对电机位置进行估算,完成汽车动力系统永磁同步电机稳定性的控制。仿真证明,所提方法能够精确估算电机位置,有效提高电机稳定性。
Controlling the stability of permanent magnet synchronous motor can effectively stabilize the running state of power train system. Traditional method ignores the estimation of position of motor,resulting in low control accuracy. A control method of stability of permanent magnet synchronous motor based on speed ring ambiguity is proposed. The table of ambiguity resolution is formed. The maximum fuzzy number of motor rotational frequency is recorded. The motor state observer is designed to formulate adjustment gain rate of motor differential value. The rotor position coordinate is estimated. The equation of current state is formed to obtain differential-difference value of current. Considering the rotor angle error,we obtain phase compensation threshold of motor and estimate the motor position. Thus,the stability control of permanent magnet synchronous motor of power train system is completed. Simulation results show that the proposed method can accurately estimate the position of motor and effectively improve the stability of motor.
