A novel adaptive event‐triggered scheme for network descriptor systems with randomly occurring uncertainties and nonlinearities

Abstract

SummaryThis article investigates the problem of event‐triggered control for network descriptor systems with randomly occurring uncertainties and nonlinearities. First, a novel adaptive event‐triggered scheme (AETC) is introduced to save more limited network resource. Second, by considering the network‐induced delay, randomly occurring uncertainties and nonlinearities, and the adaptive transmission scheme, a delay system method is used to build a novel time‐varying delay system model. Based on this model and Lyapunov function technology, sufficient stability conditions to verdict admissible and stabilization conditions to codesign the controller gain and the weighting matrix of the adaptive transmission scheme are obtained in terms of linear matrix inequalities. Finally, a numerical simulation example and a comparing example are employed to illustrate the effectiveness and the advantageous performances of the proposed AETC.
