Fixed-time consensus based cooperative control for multi-agent systems

Multi-agent systems have offered advantages such as robustness and energy saving due to the capability to cooperatively fulfil complex tasks. One fundamental research topic of cooperative control is consensus, which designs distributed controllers to achieve agreement on states such as velocity. Most current work can only achieve consensus over an infinite time horizon or in a finite time that depends on initial states, which fails to meet specific convergence requirement in an unknown environment. To address this issue, we investigate the consensus in a fixed-time framework, which provides an estimated bound of settling time without dependence on initial states.
