Abstract: This talk deals with the optimal control of the linear wave equation. The controls are chosen from the space of L2 functions in time with values in the space of Radon measures. Such controls are distributed in time and sparse in space which means their support is very small. The cost functional of such an optimal control is not Frechet-differentiable but it is convex. Therefore convex analysis is used to derive optimality conditions. The regularized problem can be solved by a semi-smooth Newton-method. The regularized optimal control problem is discretized by finite elements. Some numerical experiments show the sparsity of the optimal controls. [hide abstract] | |
