A linear-quadratic problem of optimal control over the heat conductivity process

Abstract

The problem of minimization of a quadratic functional on solutions of the second boundary-value problem for the heat equation is considered. The method of Lagrange multipliers is applied to research the formulated optimization problem. Such approach has given a chance to obtain the necessary conditions of optimality. On the basis of these conditions, the integro-differential Riccati equation with partial derivatives is deduced. The solution of this equation is presented in the closed form.
