The solution to an optimum control problem is often determined by ful$lling necessary conditions for the optimality. It usually amounts to solving a two-point-boundary-value problem. Most computational schemes used for the solution are based on the first-order variation of performance index (PI). In

โฆ Synopsis
A time-optimal problem for a second-order non-linear system with one degree of freedom is considered. The system describes the dynamics of an inertial object under the action of a control force of limited modulus which appears linearly and a perturbing force which is periodic in coordinate. The terminal set represents points on the abscissa of the phase plane, and the distance between two neighbouring points is equal to the period of the perturbing force. An estimate is obtained for the amplitude of the control for which the control has the simplest structure: the number of switchings is not greater than one.

Various types of sufficient conditions of optimality for non-linear optimal control problems with delays in state and control variables are formulated. The involved functions are not required to be convex. A secondorder sufficient condition is shown to be related to the existence of solutions of a R
