Abstract:

Considering a class of networked control systems (NCS) with generalized uncertainty and nonlinearities, a control strategy is presented, which is based on robust adaptive control and remote feedback control. Firstly, a robust function η1 is introduced to compensate the generalized uncertainties and nonlinearities. The adaptive tuning rule of parameter is designed by Lyapunov stability theory and the uniformly bounded stability and exponential convergence of the closed-loop error system can be obtained. Then the state feedback control is utilized to the NCS with time-delay, and the stability of the closed-loop NCS is effectively guaranteed by Lyapunov stability theory. Finally, The simulation results show that this method is very effective.

Key words: robust adaptive, NCS, Lypunov stability, uncertainty, time delay
