Hybrid-triggered interval type-2 fuzzy control for networked systems under attacks

Abstract

In this paper, the security control problem is considered for nonlinear networked control systems under cyber attacks. The nonlinearities are described by interval type-2 fuzzy models. To enhance bandwidth utilization and improve network control performance, a hybrid-triggered scheme is proposed. The networked control systems contain parametric uncertainties and time delays and are subject to external disturbances and cyber attacks. A hybrid-triggered-based control method is established to ensure the robust stability and a prescribed performance of the resulting closed-loop systems against attacks. Numerical simulation and a practical example of the bolt-tightening tool are provided to illustrate the effectiveness of the new control design method.
