Abstract: The model of the areodynamic missile can be described as a block diagonal construction with four layers.After getting an affine form of 1st and 2nd layers,an affine form with four layers of the missile is gotten in this paper.By using the form, this paper develops a procedure called sliding model block diagonal controller, which realizes a design of a nonlinear system of a missile. The simulation shows that the procedure has a powerful robustness for the model.
