摘要
针对滑模变结构直流调速系统在负载扰动作用下存在静态误差这一问题,本文设计了负载状态观测器,对滑模变结构控制器输出进行补偿,消除了静态误差。本文还分析了负载惯量变化时,观测器和系统的工作情况。仿真实验结果表明,系统在负载力矩扰动和惯量扰动作用下,均有较好的静态和动态性能。
In order to eliminate the static error of DC speed regulation system with sliding mode variable structure control, which result from the load, a disturbance observer is designed and used to compensate the output of controller with sliding mode in this paper. Also, the paper analyses how the observer and system work when the load inertia varies. The simulation reveals that static and dynamic performance of the system is superior in resisting the load torque and inertia disturbance.
