Fixed-Time Control

This article was published as a brief paper in Automatica. In this article, the fixed-time time-varying formation tracking control problem is addressed for heterogeneous linear multiagent systems under the directed communication graph. It is assumed that the Laplacian matrix associated with the communication graph is unavailable and that the system matrices of the leader are only available to its neighboring followers.

This article was published as a paper in IEEE Transactions on Control of Network Systems. The primary objective is to design a time-varying formation tracking protocol enabling the followers to form the desired time-varying formation while simultaneously tracking the output of the nonautonomous leader in a fixed time.
