ABSTRACT
Time delay is one of the major constraints in the networked control system that has severe effects on performance and stability of closed-loop systems. In this chapter, a unique compensation technique is proposed for nonlinear networked control system in the discrete-time domain, which compensates the deterministic type of network-induced delay. The communication delay within networks between sensor, controller, and actuator channel is nullified by Thiran’s approximation rule. The discrete-time sliding mode control algorithm derived using proposed sliding surface proves to be more robust, as it is insensitive to matched uncertainty and network-induced delay. The stability of closed-loop nonlinear NCS is assured through Lyapunov function. Finally, simulation results ensure the effectiveness of the proposed method in the presence of system uncertainties (network-induced delay and matched uncertainty).
