Abstract

In this paper, the control problem of spinning formation deployment for space triangle tethered formation systems is studied at the predefined-time convergence. First, based on the Euler-Lagrange dynamic model, a nominal predefined-time sliding mode controller is proposed for formation deployment, whose convergence time can be tuned by the setting-time parameter in advance. Second, a novel predefined-time disturbance observer is designed to estimate the lumped disturbances. Moreover, the stability of the predefined-time disturbance observer and the predefined-time controller is proved by the Lyapunov theory. The simulation results of predefined-time convergence show that the proposed control mechanism is successful.
