摘要 构造了一类多调和涡流最优化控制问题(MECOC)的新的预处理子.结合新的预处理子对系数矩阵进行预处理后使用Krylov子空间方法,如GMRES方法求解,并分析了预处理矩阵的特征值分布情况.数值实验验证了理论结果的正确性,并说明了新的预处理子的有效性. 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.
