Mixed Event/Time-Triggered Static Output Feedback L2-Gain Control for Networked Control Systems

Abstract

This paper considers the design of mixed event/time-triggered controllers for networked control systems (NCSs) under transmission delay and possible packet dropout. Assuming that a conventional delayed static output feedback L2-gain controller exists, we propose an output-based mixed event/time-triggered communication scheme for reducing the network traffic in a NCS. Moreover, we show that a conventional delayed static output feedback L2-gain controller can be obtained by solving a linear matrix inequality with a matrix equality constraint. A numerical example is proposed for demonstrating the theoretical results.
