Abstract:

With the help of a sympletic technique the concept of a field of extremals in the classical calculus of variations is generalized to optimal control problems. This enables usto get new optimality conditions that are equally suitable for regular, bang-bang, and singular extremals. Special attention is given to systems of the form \dot{x} = f_0 (x) + u f_1 (x) with a scalar control. New pointwise conditions for optimality and sufficient conditions for local controllability are obtained as a consequence of the general theory.
