The differentiable stability with respect to \(\epsilon\) for the optimal control problem \[ \min (1/2)\int_{\Omega_{\epsilon}}(y-z_ d)^ 2dx\quad +\quad (\alpha /2)\int_{\Omega_{\epsilon}}u^ 2dx\quad over\quad L^ 2(\Omega_{\epsilon}), \]
\[ -\Delta y=u\text{ in } \Omega_{\epsilon},\quad y=0\text{ on } \partial \Omega_{\epsilon} \] is considered. By finding an expression for the closure of the tangent cone to the set \[ K=\{\phi \in H^ 2(\Omega_{\epsilon})\cap H^ 1_ 0(\Omega_{\epsilon})| \quad \phi \geq a\quad q.e.\text{ in } \Omega_{\epsilon}\} \] the problem is reduced to the solution of a related optimal control problem over a certain cone.
