Summary: This research focuses on a regional optimal control problem of a bilinear wave equation evolving on a spatial domain \(\Omega\subset\mathbb{R}^d\), where \(d\geq 1\). The equation is excited by bounded controls that act on the velocity term. The main objective of this study is to minimize a functional cost, which involves tracking a desired state within a subregion \(\omega\) of \(\Omega\) and the energy term over the time interval \([0,T]\). We successfully prove the existence of an optimal control that we characterize as a solution to an optimality system. Additionally, an algorithm for the computation of such a control is given and successfully illustrated through simulations.
