基于改进hp自适应RPM的客机最速爬升轨迹优化OA北大核心CSTPCD
THE FAST CLIMB TRAJECTORY OPTIMIZATION OF AIRCRAFT BASED ON IMPROVED HP ADAPTIVE RPM
针对客机最快时间爬升优化问题,采用改进hp自适应Radau伪谱法将客机爬升连续时间最优控制问题离散化为非线性规划问题进行求解.实验仿真结果验证,优化得到的客机爬升轨迹在满足客机性能约束以及乘客乘机体验的前提下完成最快时间爬升,达到巡航高度以及巡航速度.与hp自适应Radau伪谱法相比,在保证优化解最优性的基础上,以更高的求解效率优化客机爬升轨迹.
Aimed at the optimization problem of the fastest time climb of the passenger aircraft,the improved hp adaptive Radau pseudospectral method(RPM)is used to discretize the continuous-time optimal control of passenger aircraft climb into a nonlinear programming problem to solve.The experimental simulation results verify that the optimized aircraft climbing trajectory can complete the fastest time climbing under the premise of meeting the performance constraints of the passenger aircraft and the passenger experience,and achieve cruise altitude and cruising speed.Compared with the hp adaptive Radau pseudospectral method,the improved method can complete the optimization process with higher solving efficiency on the basis of ensuring the optimality of the optimization solution.
