Stochastic gradient particle swarm optimization based entry trajectory rapid planning for hypersonic glide vehicles

Entry trajectory planning based on three-dimensional acceleration profile guidance

A high accuracy longitudinal and cross range analytical prediction method based smooth gliding reentry guidance method comprises step 1, planning a guidance scheme of a rapid descending section; step 2, planning a guidance scheme of a smooth gliding section; step 3, planning a guidance scheme of a trajectory downward pressing section. The invention also provides an energy based analytical solution of the longitudinal range, the cross range and the course angle. A method for solving the analytical solution comprises step 1, establishing a motion equation of a reentry problem of an aircraft; step 2, establishing the process constraint and the terminal constraint of the reentry problem; step 3, introducing a generalized equator and a generalized meridian; step 4, linearizing the motion equation; step 5, solving the analytical solution; step 6, verifying the feasibility of the analytical solution. The high accuracy longitudinal and cross range analytical prediction method based smooth gliding reentry guidance method can guide the aircraft to fly to assigned height with certain distance far from an object and satisfy the corresponding process constraint, end speed constraint and azimuthal angle error constraint and is good in robustness.
