The guaranteed cost of networked control systems with long time delay is researched. Using the algorithm of augmented vectors, the form of the state equation of the system is changed and it becomes more simple. Then the corresponding performance index is given. Finally, a suitable guaranteed cost control law of the NCSs (Networked Control Systems) is designed by simple matrix inequalities. The results meet the stability of the system and the requirement of performance index. An simulation example is employed to illustrate the validity of the method.

Guaranteed Cost

This paper deals with the problem of guaranteed cost control for a class of nonlinear networked control systems (NCSs) with time-varying delay. A guaranteed cost controller design method is proposed to achieve the desired control performance based on the switched T-S fuzzy model. The switching mechanism is introduced to handle the uncertainties of NCSs. Based on Lyapunov functional approach, some sufficient conditions for the existence of state feedback robust guaranteed cost controller are presented. Simulation results show that the proposed method is effective to guarantee system’s global asymptotic stability and quality of service (QoS).
