摘　　要：基于复合增量式编码器的永磁同步电机伺服控制,提出一种转子相位检测和编码器校正方法。根据复合增量式编码器的工作原理,给出基于霍尔信号边沿实现初始定位误差快速修正的转子相位检测方法。通过对编码器参考信号标定及参考信号相位对齐实现编码器的自动校正。该方法在FPGA硬件平台进行验证,实验表明,提出的方法可以保证永磁同步电机的正常启动和稳定运行。Based on the servo control of permanent magnet synchronous motor with composite incremental encoder,a rotor phase detection and encoder correction method is proposed in this paper.According to the principle of composite incremental encoder,a rotor phase detection method based on Hall signal edge to quickly correct the initial positioning error is presented.The automatic calibration of the encoder is realized by calibrating the reference signal and the phase alignment of the reference signal.The method is verified on FPGA hardware platform,and the experiments show that the proposed method can ensure the normal start and stable operation of PMSM.
