The Allocation Control of Lateral Jet System of Flight Vehicle Based on Integrated Guidance and Control Model

摘要

In order to achieve accurate interception of target in near space, this paper proposes an allocation control method based on the integrated guidance and control model of flight vehicle for lateral jet actuator. Combined the relative kinematics between vehicle and target with the nonlinear dynamics of vehicle, a model of integrated guidance and control of flight vehicle is established firstly. The adaptive dynamic surface control (ADSC) law, then, is synthesized based on the built integrated model for desired target interception performance. By integer programming method, the direct force generated by lateral jet system shapes the ADSC value by manipulating the lateral jets mounted on the vehicle. Based on Lyapunov theory and the trick of quantitative input, the stability of the closed-loop system under direct force is proved. Finally, the feasibility of the designed method is verified by numerical simulation.
