Stabilization of Controller-Driven Nonuniformly Sampled Systems via Digital Redesign

Abstract

This paper deals with the stabilization problem of nonuniformly sampled systems, assuming that the controller/scheduler can select the sampling period. In this setting, we proposed a sampling-period-varying state feedback controller that stabilizes the closed-loop system for arbitrary selection of bounded sampling periods. The proposed controller is based on the digital redesign technique, which also makes the closed-loop sampled system state response close to a pre-selected closed-loop continuous system.
