Approximate Optimal Controller for Weakly Nonlinear Evolutionary Equation of Parabolic Type.

We consider the optimal control problem for solutions of the parabolic equation with the right-hand side of the form ε F (y), where ε > 0 is a small parameter, with the coercive objective functional and bounded control. We use the formula of the optimal controller of the unperturbed problem and substantiate the form of the approximate controller with switching for the original problem. [ABSTRACT FROM AUTHOR]
