Abstract: A new preconditioner for a class of multi-harmonic eddy current optimal control (MECOC) problems was constructed.The new preconditioner for the coefficient matrix in the Krylov subspace method such as GMRES was used to analyze the distribution of the eigenvalues.Numerical experiments were used to verify the correctness of the theoretical results,and showed the efficiency of the new preconditioner corresponding to the new method.

Key words: multi-harmonic eddy current, optimal control problem, distribution of eigenvalues, GMRES method, preconditioner
