Penetration Trajectory Optimization of Hypersonic Gliding Vehicles with Multiple Constraints

The penetration trajectory optimization problem of hypersonic gliding vehicles (HGV) with multiple constraints is investigated. Firstly, the attack-defense confrontation models are established, where the HGV is required to achieve effective penetration under interception missile using Proportional Navigation Guidance (PNG) method. Then the original penetration trajectory optimization problem under multiple constraints is converted into a second-order cone programming (SOCP) problem through linearization, discretization and convexification manipulation. The online sequential convex optimization algorithm is used to solve the SOCP problem. Finally, numerical simulations are given to demonstrate the effectiveness of the method and penetration effect.
