摘　　要：提出一种工作原理同频率综合器相似的直流电机恒速控制用锁柏环路。介绍了该锁柏环路的基本构成、工作原理和设计方法，并对其进行了实验研究。通过该系统对开环转速精度低于0．3％（1σ）的直流力矩电机进行控制，可将其转速精度提高100倍，达到0．003％以上（1σ）。This paper an inexpensive phase - locked loop for the constant speed control of a DC motor , it operates on the similar principle to that of a frequency synthesizer. Besides an introduction to its basic configuration, operation principle, system design and simulation, an experimental study is completed. The experimental result shows that by using such a control system the speed accuracy of a DC torque motor with open loop speed accuracy lower than 0.3%(1σ) can be improved to higher than 0.333%(1σ).
