摘　　要：在考虑定子电阻及交叉耦合项的条件下对高频脉振电压注入法进行理论分析,推导出转子位置误差表达式,并对估计位置进行误差补偿,提出了高频脉振电压注入法的位置估计误差补偿策略。该方法与传统的脉振高频电压注入法相比,考虑并减小了定子电阻以及交叉耦合项的影响,使高频脉振电压注入法对永磁同步电机运行在中低速下时的转子位置估计更加准确。仿真验证结果表明了该方法的有效性。The high-frequency pulsating voltage injection method was theoretically analysed under consideration of the stator resistance and cross-coupling term. The expression of the rotor position error was deduced and on the basis the estimated position error was compensated. A position error compensation strategy of the high-frequency pulsating voltage injection method was proposed. Compared with the conventional high-frequency pulsating injection method this method, considers and reduces the influence of the stator resistance and the cross-coupling term, and makes the high-frequency pulsating injection voltage method more accurate in estimating the rotor position of PMSM at medium and low speed. The simulation results verify the effectiveness of the method.
