State Feedback Controller Design of Networked Control Systems

TLDR

The paper addresses controller design for networked control systems (NCS). It proposes a delay‑dependent controller design method for NCSs. The method models both network‑induced delay and packet dropout, derives a memoryless controller’s feedback gain and the maximum allowable delay by solving linear matrix inequalities. Two examples demonstrate the effectiveness of the proposed method.

Abstract

This paper is concerned with the controller design of networked control systems (NCS). A new model of the NCSs is provided under consideration of both the network-induced delay and the data packet dropout in the transmission. In terms of the given model, a controller design method is proposed based on a delay-dependent approach. The feedback gain of a memoryless controller and the maximum allowable value of the network-induced delay can be derived by solving a set of linear matrix inequalities. Two examples are given to show the effectiveness of our method.
