不确定采样系统的鲁棒镇定控制器设计

Design of Robust Stabilization Controller for Uncertain Sampled-Data Systems

讨论不确定采样控制系统的鲁棒稳定和镇定问题。通过将采样控制系统变换为具有分段连续时滞的线性模型,基于Lyapunov-Krasovskii泛函方法,获得了系统的鲁棒稳定性条件,给出了状态反馈镇定控制器的设计方法。最后,数值例子表明了本方法的有效性;且相比于文献[6]中所提方法得到的结果,本方法更优越。

Discusses the robust stabilization of uncertain sampled-data control system. By transforming sampled- data control system into a linear model of segment continuous time delay and based on Lyapunov-Krasovskii functional method, obtains the system robust stabilization conditions and presents the design method of state feedback stabilization controller. The numerical instance demonstrates the effectiveness of the proposed method, and comparing to the result from Reference [6], the method is super.
