摘　　要：在内置式永磁同步电机(IPMSM)的无位置传感器控制系统中,状态观测器的收敛性能与转子位置信息提取环节对驱动系统性能起了决定性的作用。为了提升电机在不同转速运行时估算转子位置信息的精度,提出了一种静止坐标系下的自适应全阶Luenberger观测器用于电机扩展反电动势估算与转速信息提取。通过对全阶Luenberger观测器与自适应转速估算环节的控制参数分级式设计,确保了电机运行于不同转速时估算转子速度的准确性并且抑制了噪声信号对估算转子转速信息的干扰。实验结果验证了所提方法的有效性。In the position sensorless control system of interior permanent magnet synchronous motor(IPMSM),the convergence performance of the state observer and the extraction link of rotor position information are decisive in the performance of the drive system.In order to improve the accuracy of the estimated rotor position information when the motor operates at different speeds,an adaptive full-order Luenberger observer is proposed in the stationary coordinate system which estimates the extended electromotive force and speed information of the motor.Through the hierarchical design of the full-order Luenberger observer and the adaptive speed estimation link,the accuracy of estimated rotor speed is ensured when the motor operates at diferent speeds and the interference of noise signals on the estimated rotor speed information is suppressed.The experimental results verify the effectiveness of the proposed method.
