变结构调节器在双闭环直流调速系统中的应用

Application of Variable-structure Regulator in Double Loop DC Motor Control System

本文根据变结构控制的基本思想 ,针对双闭环直流调速系统设计了一种变结构P -PI调节器 ,取代常规系统的速度调节器 (PI) ,成功地解决了转速超调问题。实验结果表明 ,变结构调节器能使系统获得优良的动态和静态特性 ,而且调节器的设计简单 。

According to the basic principle of the variable structure control, a variable structure P-PI regulator is designed for the double loop DC motor control system(DLDCMCS).It takes the place of conventional speed regulator(PI)and solves the speed overshoot problem in the DLDCMCS. Experiments show that the new regulator can present the system with excellent static and dynamic performance and is easy to be designed and adjusted for use.
