Aimed at the guidance requirements of some missiles which attack targets with terminal impact angle at the terminal point, a new integrated guidance and control design scheme based on variable structure control approach for missile with terminal impact angle constraint is proposed. First, a mathematical model of an integrated guidance and control model in pitch plane is established, and then nonlinear transformation is employed to transform the mathematical model into a standard form suitable for sliding mode control method design. A sufficient condition for the existence of linear sliding surface is given in terms of linear matrix inequalities (LMls), based on which the corresponding reaching motion controller is also developed. To verify the effectiveness of the proposed integrated design scheme, the numerical simulation of missile is made. The simulation results demonstrate that the proposed guidance and control law can guide missile to hit the target with desired impact angle and desired flight attitude angle simultaneously.
