An Observer-Based Fixed-Time Consensus Control for Second-Order Multi-Agent Systems With Disturbances

Abstract

This brief considers the fixed-time consensus problem of second-order multi-agent systems with disturbances. With the proposed observer, the state information can be exactly estimated through output information in fixed time with the effects of bounded disturbances, and the second-order multi-agent system can also reach consensus in fixed time without using any velocity information. Finally, a numerical example is given to illustrate the effectiveness of the theoretical result.
