英文摘要：

To realize an trajectory composed of boost phase,cruise phase and diving attack phase for a kind of NSHSV（Near-Space Hypersonic Vehicle） to attack targets with great maneuverability,a PSO（Particle Swarm Optimization）algorithm was adopted to carry out the integration design and optimization for solid rocket booster and boost trajectory.During cruise phase,a proportional navigation guidance law based on three-dimensional virtual target was used in the latitudinal plane,and a sub-optimal guidance law based on singular perturbation theory of nonlinear system and virtual target method was developed to control the vehicle in longitudinal plane.An optimal guidance law based on stochastic jump system control theory was adopted in the diving attack phase.Three-dimensional whole trajectory simulation shows that all the guidance laws designed were suitable,and the middle guidance laws join the boost phase and diving attack phase properly,and the terminal guidance law can achieve the aim of attack great maneuverability targets effectively.
