A Fast, Robust Numerical Method for Solving Optimal Control Problems
Generalized Lagrange Multiplier, combined with QuasiNewtons method, is proposed for fast solving terminal constrained optimal control problems. The control variables are discretized and the optimal control problem is converted into Nonlinear Programming (NLP) with 4th Admas predict-modification scheme as integrating procedure. Generalized Lagrange Multiplier (GLM) is introduced to eliminate constraints in NLP, and the obtained unconstrained NLP is solved with Quasi-Newtons method. Numerical experiments on a simple nonlinear optimal control problem and the complicated lunar soft landing problem demonstrate efficiency, robustness and good accuracy of this method.
