Modified Quasilinearization Method for Optimal Launch Mission Planning Problems

摘要

Optimal launch mission planning is one of the most important engineering fields where optimization tools and optimal control theory have found routine application. Optimal control theory is critical for launch mission to meet mission requirement such as minimum time, minimum fuel requirement, minimizing undershooting and so on. Compared to traditional off-line launch mission planning, on-line launch mission planning could generate guidance plan with respect to the current situation of the vehicles to enhance the guidance precision greatly and reduce the risks resulted by unpredictable events, while the core issue of on-board launch mission planning is how to solve the corresponding Two-Point Boundary-Value Problem (TPBVP) quickly, efficiently and precisely. We intend to introduce a stable algorithm here with a verified convergent ability to handle optimal launch mission planning problems with relatively little time consumption.
