Design of Guidance Law for Glide Vehicle under Terminal Velocity Constraint
In order to solve the guidance problem of glide vehicle under terminal velocity constraint,two guidance methods are proposed after analyzing the deceleration effect of lateral overload in this paper.First-ly,a lateral maneuvering model is established and the effect of lateral maneuvering motion on energy dissi-pation of the aircraft is analyzed,and then using lateral maneuvering overload to control the terminal veloc-ity is proposed.Secondly,in order to accurately control the terminal velocity,guidance methods based on flight speed correction and neural network are proposed respectively,and six degrees of freedom simulations are implemented.The simulation results show that the guidance methods proposed in this paper can accu-rately control the terminal velocity of the aircraft under the constraint of impact angle.The guidance method based on flight velocity correction is easy to implement in engineering practice,and the guidance method based on neural network has better control effect and the ability to deploy online.The terminal velocity con-straint guidance methods proposed have good engineering applicability and have reference significance for the guidance system design of this kind of glide vehicle.
