Research on penetration technology of high-speed aircraft based on optimal control
In the background of air combat,the high-speed aircraft's penetration technology based on the optimal control theory is studied.In this paper,the high-speed aircraft motion model,inter-ceptor motion model and relative motion model are established respectively.In order to achieve the penetration,the rate of line of sight angle between high-speed aircraft and interceptor is designed to become infinity at a certain moment,which is used as the terminal constraint.Considering the mini-mum energy control of the high-speed aircraft,the performance index function is established.Based on the optimal control theory,a penetration guidance law is designed.The simulation results show that high-speed aircraft which adopts the optimal penetration guidance law can penetrate the inter-ception of interceptor.Besides,the control energy is less than that required in the serpentine ma-neuverability and square wave maneuverability penetration.
