Contrôlabilité exacte et homogénéisation. I. (Exact controllability and homogenization. I). (French) Zbl 0659.49002
The author presents a problem concerning an asymptotic behavior of evolution operators of hyperbolic type or of Petrowsky’s type, depending of a parameter \(\epsilon\). The parameter \(\epsilon\) is related with rapidly varying coefficients in the framework of homogenization theory.
The author studies for these operators the exact controllability problem. The main result is that the optimal control limit for the rapidly varying systems is the optimal control for the homogenized system.
