Derives necessary second-order optimality conditions for optimal control problems.
Enhances understanding of controllability beyond linear approximations.
Abstract
The paper puts forward sufficient conditions for local controllability of a control dynamical system. The results obtained are meaningful in the case when the linear approximation to this system is not completely controllable. As a corollary, we obtain necessary second-order optimality conditions for a general optimal control problem.
