本文提出了一种新的方法，用于具有时变时滞的采样数据不确定系统的稳定性分析和控制器综合。在我们以前的工作中，我们已经导出了具有小于一个采样周期的有界不确定时变时滞的采样线性系统的稳定性判据，并提出了这类系统的静态状态反馈设计方法。本文试图从鲁棒稳定性的观点出发，导出具有参数不确定性系统的推广。数值算例验证了所得到结果的有效性和实用性，包括小车-倒立摆系统的镇定。
This paper proposes a new approach for the stability analysis and controller synthesis of sampled-data uncertain systems with time-varying delay in the input. In our previous works, we have already derived a stability criterion for sampled-data linear systems with bounded uncertain time-varying delay shorter than one sampling period and proposed a design method of static state feedback for such systems. This paper attempts to derive the extensions for systems with parameter uncertainties from the viewpoint of robust stability. The validity and usefulness of the obtained results are evaluated by numerical examples, including stabilization of a cart-inverted pendulum system.
