Summary: This paper investigates the distributed second-order finite-time adaptive containment and bipartite containment control for multi-agent system with disturbance and nonlinear function under undirected graph. Firstly, two controllers based on terminal sliding mode are designed to achieve finite-time adaptive containment and bipartite containment control. Then, desired finite-time containment and bipartite containment protocols are proposed and settling time can be estimated. It is proven that the settling time of finite-time containment is associated with the initial state. The feasibility of the theory is demonstrated through simulation experiments.

Summary: This study investigates the finite-time containment control problem of second-order nonlinear multi-agent systems with disturbances. Assuming a directed network topology among agents, a robust event-triggered terminal sliding mode controller is designed to handle the disturbances and achieve the accessibility of sliding manifold and consensus tracking. The Zeno-behavior of triggering time sequence is also excluded.

Summary: This paper studies the finite-time consensus tracking problem of multi-agent systems (MASs) with unknown follower's states in the presence of actuator attacks. The states of each follower are approximated using appropriate observers. The FTCT problem of MASs in two stages of sliding mode dynamic is discussed by introducing partitioning strategy. The optimization problem is efficiently solved by genetic algorithm. The effectiveness and applicability of the proposed control method are illustrated through simulation results.

Summary: This paper addresses the finite-time consensus problem for multi-agent systems with nonlinear dynamics under Euler digraph. A sufficient condition is proposed to achieve finite-time consensus, and it is found in the study that adding communication connections or increasing feedback gains is an effective way to reduce the settling time. Numerical simulations are presented to verify the effectiveness of the obtained theoretical results.

Summary: This paper investigates the scaled consensus problem for discrete-time multi-agent systems using the event-triggered sliding mode control approach. The problem considers unknown external bounded disturbance and time-varying state delay. A new event-triggered integral sliding surface function is introduced to handle the external disturbances. A distributed event-triggered control method is integrated with sliding mode control to address the energy-constrained issue. A sufficient condition is established to ensure a predefined H-infinity performance for the system. An event-triggered sliding mode control protocol is developed to guarantee the state trajectories of all agents approach the dictated scales in the discrete-time multi-agent systems.

Summary: This article investigates the bipartite synchronization problem of multi-agent systems (MASs) under deception attacks. A pinning delayed-impulsive control scheme is proposed to solve the synchronization problem caused by deception attacks in MASs, where the transmitted data information is modified and the data integrity is destroyed. Time delay utilization technology is used to exploit the gain effect of time delay on the stability of the system. By selecting appropriate time delay parameters, the convergence speed of the system is effectively improved. Cooperative and competitive interactions between agents are also considered. Theoretically derived sufficient conditions of bipartite mean-square bounded synchronization of MASs under deception attacks are obtained. Finally, numerical simulations are conducted to validate the correctness and effectiveness of the proposed results.

Summary: In this article, a method called adaptive slope sliding mode control is proposed to increase the response speed of system outputs. By constantly changing the slope of the surface, the difference between the surface and the state is minimized, leading to faster convergence of states. Compared to fixed slope methods, this approach not only improves the response speed of the system, but also increases output accuracy. To evaluate the effects of adding a variable slope to sliding mode controllers, the proposed controller is tested on grid synchronization of a wind turbine system.

Summary: This paper focuses on distributed fixed-time tracking consensus and containment control problems of second-order multi-agent systems (MASs) with directed topology. A novel nonsingular sliding-mode control method is established to enable the offline design and convergence time estimation of the consensus protocol for second-order MASs by introducing a time-varying scaling function in the design of the sliding surface. Sufficient conditions ensuring fixed-time tracking consensus and containment control of the second-order MASs are obtained using the proposed nonsingular sliding-mode control method.
