Optimization Design for Trajectory of Morphing-wing Missile Based on Hp-adaptive Pseudo-spectral Method
摘要
Abstract
In order to improve the final velocity of morphing-wing missile, a terminal trajectory optimization for morphing-wing missile was investigated. The sweep angle and attack angle were chosen as optimal control variables,and the trajectory optimization model was established with the multi-constraints of the dynamic pressure,the overload,and the bound conditions and so on. In view of the limitations of the global pseudo-spectral method to solve the optimal control problem with complex and multi-constraints,the hp-adaptive pseudo-spectral method combining the global pseudo-spectral method with hp finite element method was adopted to transform the trajectory optimization problem into a nonlinear programming problem,and the results were compared with those of the particle swarm optimization to confirm the correctness of the model and the method. The results show that the optimal trajectory of hp-adaptive pseudo-spectral method can ensure higher terminal speed and better attitude to attack targets with higher interception precision.关键词
