This paper investigates the consensus tracking problem of second-order nonlinear multiagent systems (MAS) with disturbance and actuator fault by sliding mode control method. The communication topology MAS is directed only part followers have access to leader's information. First, a discontinuous protocol studied for MAS. Second, address shortcoming chattering difficulty setting gain in protocol, continuous an adaptive mechanism developed. will adjust automatically enable work well without...

The stability of a class hybrid stochastic retarded systems (HSRSs) with an asynchronous switching controller is investigated. In this model, the design relies on observed jumping parameters, which are however delayed and thus can not be measured in real-time precisely. This time interval, referred to as "asynchronous interval", Markovian dependent actual signal. sufficient conditions under system either stochastically asymptotic stable or input-to-state obtained by applying extended...
