Numerical Solution to the Optimal Control of a Gliding Parachute System.

摘要

This study is concerned with an optimal control policy for the problem of minimizing control energy and the terminal missed distance from a target at touchdown of a gliding parachute system. The bank angle of the parachute is considered as a control variable. Under the condition of a uniform wind, a systematic search on the horizontal normalized plane is completed. A certain region is computed and specified within which a feasible control solution has been found using a specific numerical scheme. The numerical method is based on a second order differential dynamic programming algorithm due to K. Martensson.
