This paper examines operation models of multiple virtual power plants (multiVPPs), aiming at unified management the multiVPP through VPP central controller, which reveals controllability as source and load in general.

This article aims at the leader-following secure consensus problem of nonlinear multiagent systems (MASs) with switching topologies, where agents are not only suffered from aperiodic malicious denial-of-service (DoS) attacks but also affected by instantaneous disturbance external environment.

Abstract In this paper, we consider event‐triggered control for linear singularly perturbed systems. A composite controller is proposed based on the decoupled slow and fast subsystems which are triggered simultaneously. Two internal dynamic variables introduced in mechanism. The results indicate that systems can achieve asymptotic stability with control. addition, triggering time intervals have a finite lower bound independent of initial states, thus Zeno phenomenon excluded. efficiency...

The under consideration ensures also that is achieved overall guaranteed cost. Since each system involves processes evolving on both fast and slow time scales, two Zeno-free mechanisms are designed to independently decide sampling transmission instants states, respectively. As first step, we event-triggering protocol in ideal/nominal case...

Dear Editor, This letter investigates the prescribed-time stabilization of linear singularly perturbed systems.
