Regularity of components in optimal design problems with perimeter penalization

Calculus of Variations and Partial Differential Equations, 2003
The paper deals with optimal design problems of the form first considered in [\((*)\) \textit{L. Ambrosio} and \textit{G. Buttazzo}, Calc. Var. Paratial Differ. Equa. 1, No. 1, 55--69 (1993; Zbl 0794.49040)]. More precisely, the energy \[ E(u,A)= \int_\Omega \sigma_A|\nabla u|^2 dx+ \int_\Omega fu\,dx+ \text{Per}_\Omega(A)+ C|A| \] is considered, where

Optimal control of parabolic problems with state constraints: a penalization method for optimality conditions

Applied Mathematics & Optimization, 1994
The author studies state constrained optimal control problems with parabolic evolution equations. Optimality conditions are derived where the state and control expressions have been decoupled. The approach used is to consider a family of problems where deviation of the dynamics from feasibility is penalized through a parameter \(\varepsilon ...

A Penalization Method for Optimal Control of Elliptic Problems with State Constraints

SIAM Journal on Control and Optimization, 1992
This paper studies control problems for elliptic systems. A typical examples is to minimize the functional \(J(y,u)=\frac12\| y- z\|^ 2_ 2+\frac12\| u\|^2_2\) for some \(z\) in \(L^2(\Omega)\), over all \(u\) in some admissible subset of \(L^2(\Omega)\) and \(y\) in a convex subset of \(L^2(\Omega)\) with \(y\) determined from \(u\) by the boundary ...
