摘要
本文介绍了一个由单片微机控制的IGBT-PWM直流调速系统,系统采用单闭环结构,省去了电流环,而电流环的作用则由反电势跟踪控制来取代,使系统在动态过程中输出最大电流,以加快过渡过程。由于用单片微机实现了全数字控制,它不仅简化了系统的结构,而且使系统具有良好的动静态特性。
The paper introduces a PWM - driver controlled by a microprocessor with an uni - loop, using back EMF tracking method to replace the current loop, which can reach a maximum current to accelerate the transient process. The digital control with a microprocessor simplifies the system so that the driver has a good static and dynamic performance.
