Tracking control problem in multiagent systems with Lipschitz nonlinearities and external disturbances

This paper investigates the tracking control problem of multiagent systems with Lipschitz nonlinearities and external disturbances that track a target with states that are not available to any of the agents. For this purpose, a distributed estimation and control algorithm (DECA) is firstly designed for each agent to estimate and track the target’s states. Then, the proposed DECA is extended based on a finite time disturbance estimator for tracking control in the presence of external disturbances. The stability analysis of suggested algorithms is also considered. Simulation examples illustrate the promising performance of the proposed algorithms.
