微机控制直流脉宽调速系统研究

Study of PWM Regulate Speed System in Direct with Minicomputer Control

本文采用MCS-51和大功率GTR构成脉冲宽度调制（PWM）直流调速系统，用单片机实现双闭环调节，配合脉冲移相、驱动等硬件电路控制，可提高系统的可靠性和抗干扰性。

：A direct speed control system using MCS-51 and GTR is presented.In the system double closed ring and trigger and drive circuit is adopted. The system,s reliablity and anti-interferency is raised with software and hardware combined.
