摘　　要：在分析内置式永磁同步电机(interior permanent magnet synchronous motor,IPMSM)在两个静止参考轴系中的高频成分数学模型基础上,研究一种基于载波频率成分法的无位置传感器控制策略。为了能够提供持续的载波频率成分信号,采用三相三角波载波SPWM调制方式。推导了该调制方式下IPMSM的载波频率成分电流方程,根据载波频率成分电流峰值表达式中包含的转子位置信息实现了对IPMSM转子位置的估算。仿真和实验结果验证了该估算方法能够准确地实现IPMSM在全速域内的无位置传感器运行。The high-frequency component mathematical models of an interior permanent magnet synchronous motor（IPMSM） were analyzed in two stationary reference frames.A rotor position sensorless control strategy was studied using carrier frequency component method.In order to provide continuous carrier frequency component signals,three-phase triangular carrier SPWM was adopted.The carrier frequency component current（CFCC） equations of the IPMSM were deduced under the modulating pattern.The peak expressions of CFCC contained the rotor position information.Based on the information,the position sensorless control of IPMSM was built.The simulation and experimental results demonstrate that the proposed method can realize position sensorless control of IPMSM over full speed range.
