【Abstract】 This paper, based on the output decoupling and variable structure control theory, deals with the angle attitude maneuver control of vertical launching tactical missile. Firstly a nonlinear simulation model is established according to the features related to the vertical launching missile. Secondly a nonlinear control law which has a good robustness and meets the required precision is proposed to solve the nonlinear coupling, fast attitude maneuver and parameter perturbation of a nonlinear simulation model for vertical missile launching control. Lastly numberical simulations prove that the presented law is effective.\;更多还原
