Integrated Missile Guidance and Control Design with Angle of Attack Constraint

Abstract

This paper proposes a composite guidance method with angle of attack constraint for the integrated guidance and control system with the problems of target maneuver, missile parameter perturbation and missile angle of attack constraint. Firstly, an integrated guidance and control system is established for the two-dimensional guidance problem.The target maneuvering and parameter perturbations about the missile are regarded as lumped disturbances, and the corresponding disturbance information is observed and estimated by using the generalized proportional integral observers.Then, using the penalty mechanism and the design idea of block backstepping, the disturbance observation information is further integrated into the design process of the controller as feedforward compensation to realize the accurate guidance under the angle of attack constraint.Finally, numerical simulation results are given to verify the effectiveness of the proposed control scheme.
