摘　　要：结合了变结构系统理论和Lyapunov设计方法,将变结构控制策略应用于直流电动机的调速,从实现的角度,采用了基于观测器重构状态的控制方案,设计了直流调速变结构控制系统。仿真结果表明,变结构控制使得直流调速系统对负载变化和自身参数扰动具有较好的鲁棒性,控制结构简单实用,其性能优于PID控制系统。It combines variable structure control theory with Lyapnov design method and applies the method of VSC to DC speed control. From implementation of control, a VSS is designed to control the speed of DC motor, which is based on Luenberger observer. Simulation results suggest that VSC design endows the system with strong robustness against its parameter variations and load disturbances. Actually this system is simple and practical while it has better performance than PID control system.
