Integrated Design of Interceptor Guidance and Control Based on Adaptive Dynamic Surface Control

By using the adaptive dynamic surface control, an integrated control law is designed for the guidance and control of interceptor during the terminal course. According to the errors appearing in the true model, the interceptor dynamics and the Engagement Kinematics are first perfected. Then the nonlinear model for the integrated guidance and control is obtained. Adaptive dynamic surface control is used for the controller design. The upper limits of uncertainties are estimated online, and the problem of differential explosion in traditional back stepping is overcome. The control law establishes a direct relationship between control objective and actuators' command. The simulation results demonstrate the validity of the proposed design.
