Trajectory planning of medium guidance based on comprehensive optimization function
In order to plan the medium glide trajectory of guided projectile,the comprehensive optimization function is constructed and used as a performance indicator for trajectory planning.Compared with the traditional performance index,the function comprehensively reflects the energy loss and maneuvering efficiency of the projectile in gliding flight,and solves the problem that the traditional performance indicator is too one-sided.To verify the effectiveness and superiority of the function,the influence of its value on the gliding trajectory is analyzed,and the problem of trajectory planning is solved based on the hp-adaptive radau pseudospectral method.The results show that taking the comprehensive optimization function as the performance index can greatly improve the terminal velocity and maneuverability of the guided projectile,which is conducive to improve the hit accuracy and damage efficiency of the projectile.In addition,the comprehensive optimization function can also be combined with the traditional performance index to construct composite optimization index,further expanding its application scope.
