Abstract
In order to study the trajectory planning problem of glide missile,the trajectory of the navigation points under the multi-constraint conditions was planned by using optimization theory. The improved Gauss pseudospectral method( GPM) was based on navigation points. The control variables and state variables were discretized by improved GPM,and the optimal control problem was converted into a nonlinear programming problem,and the problem was solved by using the improved sequential quadratic programming ( SQP ) method. When the segment path is planned by GPM,the flight time of the next trajectory is obtained via iterative method, and the efficiency of the algorithm is reduced. The improved GPM can effectively compensate the lack of time being taken as the independent variable in many trajectory planning,and it has a wider adaptability to optimize the target. The results show that the improved algorithm can accurately and efficiently plan a reasonable trajectory to meet the flight constraints.关键词
