Optimal control and applications to aerospace: some results and challenges E. Tr elat y Abstract This article surveys the classical techniques of nonlinear optimal control such as the Pontryagin Maximum Principle and the conjugate point theory, and how they can be imple-mented numerically, with a special focus on applications to aerospace problems. While preparingthe lectures, I have accumulated an entire shelf of textbooks on calculus of variations and optimal control … An optimal control problem is typically concerned with finding optimal control functions (or policies) that achieve optimal trajectories for a set of controlled differential state variables. Now we have an expression determining the value of the choice variable, x(t), and an PREFACE These notes build upon a course I taught at the University of Maryland during the fall of 1983. and ,
