State feedback stabilisation of networked control systems

Abstract

This study addresses the state feedback stabilisation problem for networked control systems (NCSs) with time delays and packet losses. By introducing the concept of ‘effective sensor packet’, a new discrete-time switched model is formulated, and the sufficient conditions for the asymptotical stability of the closed-loop system are derived. An iterative algorithm is proposed to design the corresponding stabilising controller, and the synthesis method is also extended to the servo control case. The proposed method can be easily implemented to various applications, since it is simple and has no assumptions on the time delays model and the packet losses model. Simulation and experimental results are given to demonstrate the effectiveness of the proposed approaches.
