TY - GEN A1 - Tröltzsch, Fredi A1 - Valli, Alberto T1 - Optimal Voltage Control of Non-Stationary Eddy Current Problems N2 - A mathematical model is set up that can be useful for controlled voltage excitation in time-dependent electromagnetism. The well-posedness of the model is proved and an associated optimal control problem is investigated. Here, the control function is a transient voltage and the aim of the control is the best approximation of desired electric and magnetic fields in suitable $L^2$-norms. Special emphasis is laid on an adjoint calculus for first-order necessary optimality conditions. Moreover, a {peculiar attention is devoted to propose a formulation for which the computational complexity of the finite element solution method is substantially reduced}.
