As a particular application of the optimal control, theory this paper presents an optimum design problem coming from mechanical engineering. This problem can be formulated as to determine the shape of the boundary of an elastic body in order to minimize the stress concentration near this boundary. This type of problems are solved by using an optimal control formulation in which the control is the boundary itself and the state is given by solving the equation of elasticity. The criterion, for instance the maximum value of stresses, is to be minimized by non linear programming methods. The paper presents a formulation of the problems and numerical solutions obtained on a specific example.

A solution to the complete problem of optimal voltage scheduling and control in large scale systems is presented, as an extension of the “Differential Injections Method” for optimal voltage scheduling in a single system. First, the method is enlarged to perform an optimal, feasible and secure tertiary voltage control in a single system. Then, an extension is presented to a large scale power system, with decentralized areas, of both voltage scheduling and control : Whereas it is better to perform scheduling on a global basis, if possible, an optimal, feasible, secure tertiary voltage control may easily be decentralized.
