Abstract

This paper is devoted to solving the problem of reliable (Q,S,R)-dissipative control for singular networked cascade control systems (SNCCSs) with randomly occurring cyber-attacks and actuator saturation. In order to reduce inessential communication transmissions in the network, a more common hybrid-triggered scheme is introduced to incorporate a time- and event-triggered scheme. Bernoulli distributed stochastic variables are introduced to describe the cyber-attacks and hybrid-triggered scheme, respectively. Three major factors that leads to damage the overall network security such as actuator saturation, actuator failure, and cyber-attacks are also consolidated with the proposed model. By using Lyapunov stability theory, Wirtinger-based integral inequality and stochastic analysis, a new set of sufficient conditions are derived in terms of linear matrix inequalities (LMIs) to guarantee the proposed model is asymptotically admissible and strictly (Q,S,R)-dissipative. In addition, a model of power-plant-gas turbine system based on a numerical simulation example is presented to illustrate the efficacy of the proposed control model.
