This paper addresses the issue of lag consensus of the leader-following multiagent systems with communication delays and switching topologies. Lag consensus means that the states of the followers lag that of the leader. Based on the graph theory and the common Lyapunov-Krasovskii functional method, we design a protocol ensuring the lag consensus of multiagent systems with communication delays under...

In this paper, a new extended Kalman filter is proposed for the state estimation of nonlinear networked control systems. The Extended Kalman filter based on nominal trajectory linearization is re-described as the summation of measurements, the initial value and the nominal state. For the ideal communication scenarios, the proposed EKF-MS obtains the same estimation accuracy as the EKF based on the...

In this paper, the problem of robust sliding mode control is studied for a class of discrete delayed nonlinear systems subject to randomly varying nonlinearities (RVNs) under uncertain occurrence probability. Here, the time-varying delay is bounded with known upper and lower bounds. The RVNs under uncertain occurrence probability are characterized by utilizing a Bernoulli distributed random variable,...
This paper studies boundary control for function projective synchronization of a complex sptio-temporal network with time-varying delays and nonlinear terms satisfying the Lipschitz condition. A boundary controller based on distributed measures is studied for function projective synchronization. Using Lyapunov's direct method, the problem of existence of the controller is formulated as the feasibility...
The long time-delay will result in the performance degradation of the networked control system. In this paper, a time-delay compensation method based on time stamp and fast implicit generalized predictive control is proposed. Because the differential action is introduced, this fast implicit generalized predictive control algorithm reduces the computation time and improves the performance of the control...
The average consensus problem of multi-agent systems (MASs) with switching directed network and time-varying delays is discussed in this paper, where the switching topologies are kept weakly connected and balanced. Firstly, the n-dimensional MASs model is reduced to (n-l)-dimensional subspace. Then, some sufficient conditions for average consensus are achieved based on reciprocally convex approach...

With the aid of feedback domination technique and the Razumikhin-type theorem, an output feedback controller is designed to drive the closed-loop system globally asymptotically stable in mean square. The main contributions are two folds: 1) Remove the slowly varying...
A sliding mode control approach is proposed to synchronize a class of delayed neural networks in a finite time, where the mismatched parameters and neuron activation functions are taken into account. In the controller design, a sliding mode manifold is directly defined by the synchronization error, which greatly reduces the synchronization time. Its concise design process and its ability to synchronize...
