凸极式永磁（IPM）同步电机被广泛用于电动汽车驱动系统。为实现IPM电机的大转矩启动、宽范围调速和高效率运行，该文研究了用于电动汽车的带有Hall位置传感器的IPM电机驱动控制策略。该控制策略联合了改进的Hall预估算法与一阶Hall位置算法结合的方法。仿真和实验研究表明：在电机启动时，估算出的转子位置与实际转子位置最大误差减小到0．3rad。与普通弱磁扩速控制方法相比，采用改进的弱磁扩速控制方法，增强了控制算法的鲁棒性。采用离线制表一查表的运行控制策略和平均误差电压死区补偿方法后，与交轴电流为零的控制算法相比较，电机效率提高了1％。

Interior permanent magnet (IPM) synchronous motors are widely used in electric vehicles. This paper investigates the driving control of IPM motors with Hall position sensors to realize large torque starting, wide range of speed regulation and high efficiency operation. The driving control strategy combines the improved Hall prediction algorithms with the first-order Hall position algorithms. Simulation and experimental results show that the maximum error of rotor position detection is less than 0.3 rad using the proposed strategy when the motor starts. The proposed flux weakening method has a better robustness compared with the traditional flux-weakening control. The motor efficiency is increased by 1% compared with that of the zero quadrature axis current control, when using table look-up control strategy and average-voltage dead-time compensation method.
