Nonsingular fixed-time consensus tracking for second-order multi-agent networks. (English) Zbl 1318.93010
Summary: 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 particular, the proposed framework eliminates the singularity and the settling time is assignable for any initial conditions. This makes it possible for network consensus problems to design and estimate the convergence time offline. Finally, simulation is included to demonstrate the performance of the new protocols.
