Abstract

In this paper, an approach to design of a robust nonlinear autopilot is proposed. First, a nonlinear model of missile motion which contains unknown uncertainties is derived. Then, unknown uncertainty bounds are estimated. Based on these estimates, controller parameters are updated at each step. The recursive design procedure called "adaptive backstepping and dynamic robust recursive design approach" is used to find a nonlinear stabilizing control while estimating the uncertainty parameters, and the performance is demonstrated via computer simulations
