Nonlinear adaptive control design for ship-to-ship missiles

Ship-to-ship missiles have relatively large weight and complex cross couplings between each channel and, practically, the aerodynamic uncertainties also make it difficult to analyze and control it. In this paper, an approximate missile model is presented with parametric affine structure applicable to all operating points. An approximate minimum phase dynamics is also derived. The uncertainties in aerodynamic forces are modeled into parametric form to design a nonlinear adaptive controller.
