摘要
研究了一类含有非线性扰动切换系统的鲁棒镇定问题。基于滑模控制技术,提出了降阶输出反馈鲁棒控制策略,给出了系统的滑动模态可达条件,同时设计了该条件下各子系统的输出反馈滑模控制器,并根据李雅普诺夫函数和状态增益给出了离散切换策略,确保闭环切换系统是渐近稳定的。通过数值仿真验证了设计方法的有效性。
The problem of robust stabilized control for a class of switched hybrid systems with unknown nonlinear disturbance is studied. Based on sliding mode control techniques, a decentralized output feedback robust control scheme is proposed. The sliding mode reachability condition is given. And output feedback sliding mode controller for each sub-system is designed. Furthermore, according to the values of Lyapunov function and state variables, the switching strategy is submitted to guarantee the asymptotic stability of the closed-loop system. Simulation results demonstrate the effectiveness of the proposed approaches.
