Optimal Control of a Signorini Problem
Alfredo Bermúdez, C. Saguez · SIAM Journal on Control and Optimization · 1987
In this paper we present a new method to obtain necessary conditions for optimal control problems of variational inequalities. It uses only techniques of classical convex analysis and is based on a transformation of the original problem into another one involving a linear state equation and nonconvex constraints on the state.
