摘要：

We give a sufficient condition for a bang-bang extremal (ξ) over cap to be a strong local optimizer for the minimum time problem with fixed endpoints. We underline that the conditions imply that the optimum is local with respect to the state and not necessarily to the final time. Moreover, it is given through a finite-dimensional minimization problem, hence is suited for numerical verification. A geometric interpretation through the projection of the Hamiltonian flow on the state space is also given. (C) 2004 Elsevier B.V. All rights reserved.
