TL;DR: It is shown that the proposed controller guarantees that all signals in the closed-loop system are fourth-moment semiglobally uniformly ultimately bounded, and the tracking error eventually converges to a small neighborhood of the origin in the sense of mean quartic value.

TL;DR: To effectively use the network resources, a suitable event-driven communication scheme is proposed for the networked switched systems in this paper and the applicability of the proposed filtering scheme is demonstrated via a mass-spring system model.

TL;DR: A state-estimation-based sliding mode control law is designed to guarantee the reachability of the sliding surface in finite time interval and a stochastic stability criterion is established for all admissible uncertainties, which can guarantee the error system and sliding mode dynamics to be asymptotically stochastically stable with a given disturbance attenuation level.

TL;DR: This paper examines the problem of tracking control of networked multi-agent systems with multiple delays and impulsive effects, whose results are applied to mechanical robotic systems and a relationship between the frequencies of impulses and systems' parameters is unveiled.

TL;DR: A novel integral-type fuzzy switching surface function is put forward, which contains singular perturbation matrix and state-dependent input matrix simultaneously in a transformed fuzzy SPSs such that the matched uncertainty/perturbation is completely compensated without amplifying the unmatched one.
