固定时间共识(fixed-time consensus)在多智能体系统中的重要性相对于渐近共识(asymptotic consensus)或有限时间共识(finite-time consensus)主要体现在以下几个方面: 渐近共识的局限性:在多智能体系统中,大多数先前的研究主要集中在解决渐近共识问题上。在这种情况下,共识的误差向量将以最佳的指数衰减速率收敛到零向量。
Fixed‐time consensus, intermittent communications, nonlinear protocols, multi‐agent systemsThis paper proposes a new class of nonlinear protocols for fixed‐time consensus in networked agents with directed and intermittent communications. First of all, based on the assumption of a common positive dwell...
This article focuses on fixed‐time consensus of networked Euler–Lagrange systems (NELSs) over event‐based communication under denial‐of‐service (DoS) attacks. First of all, a basic fixed‐time consensus algorithm is developed for NELSs, where a general fixed‐time communication triggeri...
This paper addresses the problem of fixed-time consensus algorithm for the second-order multi-agent systems with bounded disturbances. The proposed fixed-time protocol can ensure a fixed-time consensus. First, the control law is designed to make the true speed track the virtual speed in a fixed...
Multi-agent systemsLyapunov functionsConvergence rateThis work focuses on the fixed-time consensus problem for multi-agent systems. By employing an improved fixed-time stability theorem and Lyapunov functions, it is proved that the proposed protocols can achieve fixed-time consensus when the interaction...
This study focuses on the design of fixed-time consensus for first-order multi-agent systems with unknown inherent non-linear dynamics. A distributed control protocol, based on local information, is proposed to ensure the convergence of the tracking errors in finite time. Some conditions are derive...

This paper studies the problem of fixed-time output consensus tracking for high-order multi-agent systems (MASs) with directed network topology with consideration of data packet dropout. First, a predictive compensation based distributed observer is pres
Consensus-based strategyFixed timeEconomic dispatchIn this paper, we introduce a new economic dispatch strategy to solve the energy management problem in a smart grid which is a distributed and cooperative method. Different from the existing works,......
This paper investigates the fixed-time consensus tracking problem for second-order multi-agent systems in networks with directed topology. Global well-defined nonlinear consensus protocols are constructed with the aid of a newly-designed sliding surface for each double-integrator agent dynamics. In parti...
