Robust Constraint-Following Control for Networked Multiagent Systems With Uncertainties

Aiming to address the time-varying formation control problem of uncertain and networked multiagent systems, this article develops a novel robust constraint-following control approach, which is implemented in two steps. First, a kinematic model (i.e., kinematic constraint) for each agent is constructed by employing local tracking errors; this constraint mainly ensures formation maintenance and trajectory following. Second, based on the kinematic model, and to attenuate time-varying uncertainties, a robust constraint-following controller is meticulously designed. This controller not only ensures the strict satisfaction of kinematic constraints but also sufficiently suppresses time-varying uncertainties. Ultimately, an application to quadrotor swarm is provided to illustrate the proposed control scheme.
