Abstract
A nonlinear decoupling control method based on back-stepping design and sliding variable structure control theory was proposed in this paper according to the nonlinear and strong coupling characteristics of missile at hingh angle of attack. The affine nonlinear model of missile was firstly established, the exact linearization and input/output decoupling of system were then realized using differential geometry theory. On the basis of this, the robust controller was designed using back-stepping design and variable structure control method. Simulation results indicate that the influences caused by missile parameter uncertainties, unsuited uncertainties with known upper boundaries and stochastic interference can be effectively restrained.
