Abstract

A new Predictor-Corrector homotopy method is proposed based on a variable order predictor and a stability oriented steplength control. Predictors of different orders are combined by order controls, is developped that gives way to a significant speedup in the solution of optimal control problems. The proposed method is applied to the problem of escaping from a microburst encountered during landing approach. It can be shown that the optimized three-dimensional escape trajectory is very efficient and superior to the two-dimensional trajectory restricted to the vertical plane. Variations of aircraft and problem parameters show that superiority of lateral escape holds for many cases.
