轧机速度系统积分反步控制器的研究

本文给出了轧机速度系统的积分反步控制器设计方法，此方法通过逐步修正算法设计镇定控制器，实现系统的全局调节或跟踪．在每一步把状态坐标变换和一个已知Lyapunov函数的虚拟控制系统的镇定函数等联系起来，最终得到一个控制李稚普诺夫函数(clf).然后．基于上述方法设计了直流电机驱动的轧机速度系统非线性反馈控制器，用来说明积分反步法也适用于线性系统、仿真研究结果表明．本文所设计的反馈控制器使闭环系统稳定，且使系统具有良好的跟踪性能。

Integrator Backstepping Controller for Speed Systems of the Rolling Mill

The method of designing controllers based on integrator back stepping for speed systems of the rolling mill is presented. Through the gradually correcting algorithm, a stabilizing controller is designed and global regulation or tracking is achieved. In each step, the change of state coordinate and unperturbed function of virtual control system with a known Lyapunov function are connected and a CLF is derived finally. Then a feedback controller is developed for speed systems of the rolling mill driven by DC motor simulation results show that the designed feedback controller make the closed-loop system stable and has better tracking performance.
