摘要：Networked Control Systems (NCS) is a control system in which the sensors, controllers, and the actuators are connected via communication network. The use of communication network will lead to intermittent losses or delays of the information and may decrease the performance and cause instability. This paper presents the design of H∞ state feedback controller for NCS. The NCS is modelled as a time delay system. Two network features are considered: signal transmission delay and data packet dropout. Our objective is focused on the design of state feedback controller which guarantee asymptotic stability of the closed-loop systems. The proposed methods are given in the terms of Linear Matrix Inequality (LMI). Finally, we consider an unstable system for numerical example. It is shown that the state feedback controller proposed here make the closed-loop system stable with or without input disturbance.
