摘要
介绍了用锁相技术实现无位置传感器无刷直流电机的高精度稳速控制 ,给出了系统框图 ,并进行了稳定性分析 ,在无位置传感器无恻直流陀螺电机中应用 ,稳速控制精度达到± 5× 10 - 6 。
In this paper, the high accuracy steady speed control of the sensorless brushless DC motor is introduced, which has been realized by phase-locked loop technology. The system structure is given and the system stability is analysesed. This method has been used on sensorless brushless DC gyro motor. The steady speed accuracy of ±5×10~ -6 is obtained.
