Adaptive terminal sliding mode cooperative control for multiple missiles with input saturation

Abstract

This paper studies the robust cooperative control problem of multiple missiles subject to model parameter uncertainties, external disturbances and input saturation. Firstly, a missile formation flight system including the disturbance and input saturation is established. Secondly, an adaptive anti-saturation cooperative controller is proposed by using the terminal sliding mode control, adaptive control, digraph topology and auxiliary system. Finally, Lyapunov stability theory and numerical simulations are employed to prove that states of the closed-loop system under the presented controller are practical finite-time stable.
