Integro-Differential Riccati Equation in the Optimal Control Problem by the Process of Heat Conductivity

Автори

Riccati equations occur when solving the problems of dynamics of processes in continuous environments, problems of the theory of heat conductivity and diffusion, problems of the theory of optimal control. In case of systems with lumped parameters it is necessary to investigate the usual matrix differential Riccati equations. There are integro-differential Riccati equations for mathematical models of systems with the distributed parameters. In the majority of monographs devoted to the theory of optimum control by systems with distributed parameters, the differential Riccati equations are not considered at all. In the given article the linear-quadratic problem of optimal control is investigated by heat conductivity process. By means of the method of Lagrange multipliers we obtain necessary optimality conditions. The uniqueness of optimal control is proved. Firstly for such problem we use Dirac delta-function and obtain the integro-differential Riccati equations. The formula for calculating the solution of this equation is proposed. By means of the given formula the optimum control is presented in the closed form.
