We study a controllability problem (exact in the mechanical variables {$w,w_t$} and, simultaneously, approximate in the thermal variable $\theta$) of thermoelastic plates by means of boundary controls, in the clamped/Dirichlet B.C. case, when the 'thermal expansion' term is variable in space.
Keywords: Controllability problem, thermoelastic plates.
