Fixed-Time Output Consensus for A Class of Heterogeneous Nonlinear Systems

This paper considers the fixed-time leader-following output consensus for heterogeneous nonlinear systems. To address this problem, a fixed time convergent distributed observer is firstly proposed. Therefore, the leader's states can be obtained by followers. Then, inspired by fixed-time tracking control, a distributed control law is recursively derived with the help of the output regulation theory. Finally, to verify our design, an illustrated example is also provided.
