Fixed-time event-triggered and periodic event-triggered containment control for heterogeneous multi-agent systems under DoS attacks
This study explores the fixed-time containment control problem for heterogeneous multi-agent systems (HMASs) under denial-of-service (DoS) attacks. A continuous control scheme is provided to enable HMASs to solve fixed-time containment control problems with unknown DoS attacks and arbitrary initial conditions. To reduce the frequency of controller updates, a novel control strategy based on event-triggered conditions has been designed, which can settle the fixed-time containment control issue without requiring continuous controller updates. In the scenario where the initial states of the systems are bound, an improved event-triggered control scheme with periodic event-triggered conditions is designed, which can avoid continuous controller updates and does not need continuous system messages. Compared with many existing results, all the designed control schemes can settle fixed-time containment issues even when the DoS attacks and initial conditions are unknown. Moreover, the given event-based control schemes can avoid Zeno-behavior. Numerical examples are provided to support the results.
期刊介绍:
Founded in 1981 by two of the pre-eminent control theorists, Roger Brockett and Jan Willems, Systems & Control Letters is one of the leading journals in the field of control theory. The aim of the journal is to allow dissemination of relatively concise but highly original contributions whose high initial quality enables a relatively rapid review process. All aspects of the fields of systems and control are covered, especially mathematically-oriented and theoretical papers that have a clear relevance to engineering, physical and biological sciences, and even economics. Application-oriented papers with sophisticated and rigorous mathematical elements are also welcome.
