Abstract

This paper investigates the distributed finite-time formation problem of quadrotors using the information of relative position only. A high-gain observer is constructed to estimate the relative velocity through the relative position. Based on the estimated relative velocity, nonsingular terminal sliding mode (NTSM) protocols are designed for followers. The control protocols for the position subsystem of quadrotors are developed by the combination of the isokinetic trending law and the idempotent trending law, which guarantees the realization of finite-time formation accurately and quickly in the presence of the bounded external disturbances and internal uncertainties. Moreover, an idempotent term is introduced to the attitude subsystem, which eliminates the chattering caused by the isokinetic trending law. Finally, a numerical example is given to illustrate the effectiveness of the proposed method.
