Event-based output tracking control for networked T-S fuzzy systems under non-periodic DoS jamming attacks

摘要

This paper is concerned with event-based output tracking control for networked Takagi-Sugeno (T-S) fuzzy systems under denial-of-service (DoS) jamming attacks. First, a unified event-based augmented fuzzy switched systems is formulated, in which: 1) an output-based resilient event-triggering transmission strategy is designed to reduce network resource utilization while resisting the impact of the DoS jamming attacks; and 2) an event-based fuzzy tracking controller with the imperfect premise matching is constructed. Second, using a piecewise Lyapunov functional approach, sufficient conditions for the existence of a fuzzy secure output feedback H_∞ controller that guarantees stability and a prescribed H_∞ performance are given in terms of linear matrix inequalities.
