“…The bipartite containment consensus problem of linear multiagent systems was studied in [35], where an observer-based event-triggered control mechanism was proposed. Most recently, the authors in [36] constructed event-triggered control ensuring prescribed-time bipartite consensus of first-order multi-agent systems, where the settling time is completely preassigned and inter-neighboring communication among agents is discontinuous. However, the results of agents with single-integrator dynamics cannot be extended directly to general linear multiple agents.…”

In this paper, the practical prescribed-time bipartite consensus problem of linear multiagent systems with a connected structurally balanced signed graph is investigated by using event-triggered mechanism. Novel event-triggered control law and triggering condition are proposed for each agent, in which the sampled states of agent and its neighbors are needed. By using the algebraic graph theory and Lyapunov stability theory, it is verified that the practical bipartite consensus can be achieved at fully prespecified time with an adjustable neighborhood range. Moreover, a theoretical discussion is provided to illustrate that Zeno behavior can be avoided during the whole time span. The feasibility of the presented control strategy is validated by a simulation result.

“…Compared to continuous triggering, interval actuator triggering will inevitably weaken control performance, leading to a conflict between the number of triggers and stable behaviour. Although the PTS concept was successfully introduced in multiagent systems [29], the PPTS property has not been explored in existing eventtriggered works. Ensuring the PPTS property under an event-triggered mechanism therefore remains a challenge.…”

Finite/Fixed-time control yields a promising tool to optimize a system's settling time, but lacks the ability to separately define the settling time and the convergence domain (known as practically prescribed-time stability, PPTS). We provide a sufficient condition for PPTS based on a new piecewise exponential function, which decouples the settling time and convergence domain into separately user-defined parameters. We propose an adaptive event-triggered prescribed-time control scheme for nonlinear systems with asymmetric output constraints, using an exponentialtype barrier Lyapunov function. We show that this PPTS control scheme can guarantee tracking error convergence performance, while restricting the output state according to the prescribed asymmetric constraints. Compared with traditional finite/fixed-time control, the proposed methodology yields separately user-defined settling time and convergence domain without the prior information on disturbance. Moreover, asymmetric state constraints can be handled in the control structure through bias state transformation, which offers an intuitive analysis technique for general constraint issues. Simulation and experiment results on a heterogeneous teleoperation system demonstrate the merits of the proposed control scheme.

“…In an event‐triggered control scheme, the information transmission among agents and controller updates are determined by the designed triggering conditions [9]. Compared with continuous control and periodic control, event‐triggered control shows more advantages in reducing the communication burden and resource consumption.…”

Periodic event‐triggered bipartite consensus for multi‐agent systems with partial information transmission

This paper investigates the periodic event‐triggered bipartite consensus for the single integral multi‐agent systems. A fully distributed periodic event‐triggered protocol is designed for a general case that only partial information can be transmitted among agents. Then, we construct a state‐dependent and time‐dependent event detector to determine whether the sampled data should be sent out at sampling instants. Under structurally balanced signed digraphs, it is proved that all agents achieve consensus with the same magnitude but opposite sign. Notably, compared with the existing event‐triggered strategies, the limitation on sampling period can be removed and the Zeno behavior is automatically excluded. Finally, the simulation results illustrate the validity of the provided protocol.
