N2 - A sliding mode control algorithm based on nonlinear disturbance observer (NDO) is proposed for integrated guidance and control (IGC) system in this paper. Firstly, the IGC model is established as a linear system with mismatched uncertainties. Secondly, a NDO with finite time convergence is used to estimate the disturbances and their derivatives. Thirdly, an integral sliding mode surface is designed to obtain the rudder deflection command directly instead of the back-stepping control (BC) algorithm used in conventional IGC system, which achieves the real sense of IGC, and the stability of the system is proved strictly by Lyapunov stability theory. Finally, the superiority of the IGC method based on NDO is verified by simulation.
