Abstract:

A connection is made between the appearance of abnormal trajectories in optimal control problems and convergence difficulties of the Newton-Raphson iterative technique in producing numerical solutions to the nonlinear two-point boundary value problem in these cases. The connection is displayed in the context of a particular time-fixed optimal control problem involving an atmospheric entry vehicle for which numerical evidence has been obtained. Author
