电机速度控制系统中的锁相技术

Phase-looked Loops Technique in Motor-speed Control System

本文综述了锁相技术在电机速度控制系统中的应用,包括直流电机的锁相环控制、锁相技术在交流调速系统中的应用,最后介绍了锁相技术用于多台电机的同步协调控制.理论及实践表明,采用锁相技术可以获得极高的速度控制精度.

This paper describes the use of phase-locked loops technique in motor-speed control systems, includes the control of DC motors by phase-locked loops and the use of phase-looked loops in AC speed-adjusting systems. At last, it is discussed that phase-lo-cked loops are used to coordinate several motors. It was shown by theory and experiment that with phase-locked loops technique, very accurate speed can be achieved.
