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。
By using non-smooth analysis and fixed-time stability techniques, distributed protocols are proposed to achieve the fixed-time consensus over fixed and switching topology. Then, for a class of linear multi-agent systems, a new distributed controller is proposed to further reduce the calculation cost...

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...
The consensus tracking control problem is investigated in this paper for second-order multi-agent systems in the presence of external disturbances. A fixed-time consensus tracking control method is presented with the control parameters updated by relative information of system states. The states of mul...
