摘　　要：文章介绍了通过自比较来检测录音机主导轴单相永磁交流测速发电机反馈信号的频率变化，从而获得速度误差，并自动校正转速的一种自适应速度调节控制电路。电路简捷，精度高，抗干扰能力强，且可用于其它类型电机稳速控制。This paper proposes an self adaptive speed accommodating control circuit,which can get the speed error,and can test the change of frequency of feedback signals of the single phase ac tacho generator through self comparing and automatically corrects the speed. This circuit has the following merits,that it is simple,high accurate and has strong properties of anti disturbance and can be used to control other motors.
