Fixed-Time Leader–Follower Output Feedback Consensus for Second-Order Multiagent Systems
针对无速度测量的二阶多智能体系统，提出一种连续固定时间分布式观测器一致性协议，使系统在独立于初始条件的有限时间内达成一致，并通过李雅普诺夫方法证明稳定性。
This paper addresses the fixed-time leader-follower consensus problem for second-order multiagent systems without velocity measurement. A new continuous fixed-time distributed observer-based consensus protocol is developed to achieve consensus in a bounded finite time fully independent of initial condition. A rigorous stability proof of the multiagent systems by output feedback control is presented based on the bi-limit homogeneity and the Lyapunov technique. Finally, the efficiency of the proposed methodology is illustrated by numerical simulation.
