Fault-tolerant Control of Networked Control System with Packet Dropout and Transmission delays

Abstract

This paper deals with the problem of fault-tolerant control of networked control systems (NCSs) with packet dropout and transmission delays which is introduced by communication channel. By employing delay-dependent approach, introducing partial failure model and utilizing integral-inequality method, the integrity design of NCSs with actuator failure is analyzed. The sufficient stabilizability condition of system with memoryless networked state feedback controller is obtained. Based on this condition, the networked fault-tolerate controller can be derived by solving a set of linear matrix inequalities. Numerical examples illustrate the effectiveness of the proposed approach.
