【摘要】 针对不确定采样控制系统的跳变模型,基于定常Lyapunov函数方法研究了带输出约束采样系统的鲁棒状态反馈H_∞控制器设计问题。针对范数有界参数不确定采样系统,提出了H_∞滚动优化设计的在线算法,该算法得到了最优状态反馈H_∞控制器,且兼顾了输出约束和系统性能之间的关系,即实现了当较大扰动作用于系统时,自动降低性能以保证满足输出约束,当外部扰动恢复到通常状态时,提高系统性能以取得较好的控制效果。更多还原

【Abstract】 In this paper,the problem of designing of robust state-feedback H_∞ ,controller for uncertain sampled-data control systems with output constraints have been investigated base on jump system model of sampled-data system using constant Lyapunov function(CLF) approach.The online algorithm of the _∞ ,receding horizon optimization design for the normbounded parametric uncertain system is proposed.The optimal state-feedback _∞ ,controllers are obtained and these controller can provide a performance tradeoff with respect to output constraints,i.e.,the control strategy offers the capability of relaxing the performance level automatically in order to obey output constraints in the case of a larger disturbance.When the disturbance is restored to a usual situation,this control strategy can also improve the performance of system automatically.更多还原
