摘要
This paper investigates the finite-time consensus problem for nonholonomic multi-agent systems with unknown external disturbances. Firstly, the chained-form nonholonomic multi-agent systems are converted into two subsystems, one is first-order and another second-order. Then, the integral sliding mode-based finite-time event-triggered control laws are proposed to ensure that the states of the agents achieve consensus in finite time in spite of external disturbances. Furthermore, the inter-execution time is proved lower-bounded and the Zeno behavior is therefore naturally avoided. Finally, numerical sim-ulations demonstrate the effectiveness of the proposed protocols. (C) 2020 The Franklin Institute. Published by Elsevier Ltd. All rights reserved.
