With the rapid development of mobile devices and geographic information systems, social network data have become part of the traffic condition dissemination system,thereby influencing traffic conditions. Current research has indicated that the dissemination of traffic congestion information can partially alleviate congestion problems and thus enhance road transportation efficiency [1].

In this paper, we investigate the pth moment uniformly asymptotic stability of impulsive stochastic ftmctional differential systems by extending some Razumikhin-type theorems. Based on the Lyapunov functions and Razumikhin techniques, some criteria are established and their applications to impulsive stochastic delay systems are proposed. An illustrative example shows the effectiveness of our results.

In this paper, the issues regarding the input-to-state stability(ISS) and integral input-to-state stability(iISS) of the stochastic delayed switching systems with Lévy noise and input control(SDSS-LN-IC)are proposed by employing the comparison theorem approach, mode-dependent average dwell time(MDADT)method, delay integral inequality(DII), and Lyapunov-Razumikhin(L-R) technique. Two switching situations, namely, synchronous switching and asynchronous switching, are considered. Applying integral inequalities, sufficient stability conditions in both cases are given. Moreover, the sequences of this paper allow for the coefficients for the upper-bound expectation estimation of the infinitesimal operator to be mode-dependent,regardless of the sign and time-varying function rather than a constant, as is the case in certain existing results, which manifests the condition of the Lyapunov-Razumikhin technique in this paper is looser and less conservative. Finally, the validity and correctness of the theoretical results are verified by two examples and some simulations.

This study addresses the practical tracking problem for a class of multi-input multi-output(MIMO) uncertain stochastic systems driven by colored noises via the active disturbance rejection control approach. The extended state observer is designed to estimate in real time the unmeasurable states and the stochastic total disturbance of each subsystem, including unknown coupling system dynamics between subsystems, colored noises, and uncertainty caused by partly unknown control parameters. Active disturbance rejection controllers based on the timely estimation of the extended state observer and compensation are then designed, guaranteeing the mean square practical convergence of the tracking errors. Some numerical simulations are performed to validate the effectiveness of the proposed control strategy.

Dear editor,As a kind of hybrid systems, Markov jump systems have made remarkable progress by the researchers from the various fields in the past few decades [1]. Unlike switched systems with a definite jump signal [2], a random signal adjusts the working sequence of subsystems in Markov jump systems. Meanwhile, for networks with limited bandwidth and energy, the time-triggering scheme accelerates resource consumption. One of the effective ways of tackling this problem is to adopt event-triggering scheme (ETS)[3, 4].
