Abstract

Abstract: A state observer was designed for a class of networked control systems with a short delay， in which the sensor is timedriven， and the controller and actuator are eventdriven. The networked control systems were discretized， and a discrete model of the system was given. In addition， the determination method of asymptotic stability was given on the basis of the state observer. Sufficient conditions for the system asymptotically stable were obtained by building Lyapunov function and linear matrix inequalities. A simulation example showed the feasibility and effectiveness of the proposed method.

Key words: NCS(networked control systems), short delay, Lyapunov function, linear matrix inequality (LMI), observer
