In this article, a finite-time adaptive fuzzy consensus control problem is solved for a class of uncertain nonlinear multi-agent systems (MASs), where the agent of each follower is marked as a non-strict feedback form. During the control design, a finite-time fuzzy adaptive controller is obtained by adding power integrator techniques and integrating backstepping design. This presented adaptive fuzzy consensus control scheme can guarantee the closed-loop system semi-global finite time bounded. In addition, the tracking error converges to a small neighborhood of the origin with arbitrary switching communication topologies. Finally, the effectiveness for presented control approach can be validated by a simulation example.

This article investigates the adaptive control problem for nonlinear cyber‐physical systems with network communication encountered false data injection (FDI) attacks. To address such attacks, the attack estimate method is designed whose objective is to minimize the vulnerability of FDI attacks. This article aim to find, using the historical FDI attack, a solution with guaranteed out‐of‐sample forecasting, so as for the attacker to plan its attacks such that the worst possible action on the system measurement. The approach is to formulate a robust optimization problem using the box‐like sets, and then transform it into a linear programming model for solving problems. Consequently, under the framework of backstepping, a robust adaptive state‐feedback control method is proposed. By using Lyapunov stability theory, the proposed control scheme can guarantee that all the closed‐loop signals are globally bounded and the stabilization error converges to the origin. Finally, simulation results illustrate the effectiveness of the proposed control scheme.

This article investigates an adaptive fuzzy predefined-time fault-tolerant control problem for third-order heterogeneous vehicular platoon systems (HVPS) with actuator faults. For the purpose of approximating the unknown nonlinear functions, fuzzy logic systems (FLSs) are used. Because the maximum acceleration changes as a result of actuator faults, a quadratic spacing strategy including fault factor is considered. A predefined-time fault-tolerant controller is designed to address the impact of actuator faults. The proposed method makes use of the non-singular terminal sliding mode control (SMC) approach and predefined time stability criterion. Individual vehicle stability, string stability (SS), and traffic flow stability are all guaranteed in a predefined time. Finally, simulations illustrate the usefulness of the given results.
