摘要

In this paper, input saturation and constraints of attack angle, sideslip angle and velocity deflection angle are taken into consideration in integrated guidance and control (IGC) design for skid-to-turn missile. The novel adaptive IGC scheme is proposed by combing dynamic surface control with barrier Lyapunov function (BLF). The BLF and modified saturation function are incorporated to prevent the constrained states from overstepping the constraints. To handle input saturation, auxiliary system is constructed. According to the stability analysis, all signals in closed-loop system are uniformly ultimately bounded while the constrained states remain in the constraint sets. The performance of the proposed adaptive IGC scheme is demonstrated by nonlinear numerical simulation results. (C) 2018 Elsevier Masson SAS. All rights reserved.
