Abstract

Abstract: An introduction is given to the transfonnation of optimal control problem with state inequality constraints,control inequality constraints and tenninal constraints into static nonlinear programming problem with parameterized optimization method, and a new augmented-SWIFT is also presented.The SWIFT(Sequential Weight-Increasing Factor Tech-nique)is used in static constrained optimization problem whereas the new auginented-SWIFT is extended to calculate dynamic constrained optimal control problem,Finally,the feasibility of this algorithm is certified by an example of a reentry optimal trajectory.

Key words: optimal control, parameterized optimization method, nonlinear programming, optimal flight trajectory
