摘要
普通位置传感器在高转速下无法实现高精度的电机转子位置反馈,严重制约高速电机伺服控制发展.针对此问题,提出了一种可以在高转速下精确反馈转子位置的单对极磁电编码器,并针对其反馈滞后的特性提出了可保证控制精度的补偿方法.同时设计了实验系统,对一台600,W、4对极、额定转速20,000,r/min的永磁同步电机进行控制实验.实验结果表明,此方法有效地利用位置传感器实现了高速电机的伺服控制.
Common position sensors cannot achieve detection of the rotor position with high precision at high speed,which badly hinders the development of servo control for high-speed motors.In this paper a novel single-pole magnetic encoder has been proposed for precision feedback of rotor position of high speed motors,and a compensation algorithm for feedback lag has been put forward to ensure the control precision.Control experiment has been carried out with a permanent-magnet synchronous motor（PMSM）with 600 W,4 pairs of poles and the rated rotation speed of 20 000 r/min,and confirms the validity of vector control of high speed motor by using the position sensor proposed.
