Abstract: The paper addresses an event-triggered sliding mode control (ET-SMC) scheme under external perturbances for the nonlinear networked system. An ET-SMC based on a property that confines the sliding trajectory within the sliding region is applied to the nonlinear networked system. The application of this strategy ensures closed-loop system stability and efficient usage of channel bandwidth and reduces data packet dropouts. A comparative analysis with an event-triggered H_∞ control strategy was performed to determine the optimal strategy applicable to networked systems. The simulation results are used to generate the comparative analysis to state the efficacy of the ET-SMC over event-triggered H_∞. The nonlinear networked system's stability is demonstrated theoretically and validated by simulation.

Keywords: nonlinear system; event-triggered control; H_∞ control; sliding mode control; closed loop system.
