摘　　要：结合特征值计算,探讨了应用频域转矩方法分析线性最优励磁控制(LOEC)过程中电磁功率信号两种处理方法的异同。应用选择模式分析(SMA)方法的基本思想,发现并证明了频域转矩分析的数学实质为对应特征值函数的近似处理,其适用条件取决于文中所提出的迭代过程的收敛性。上述结论通过一个实例计算得到了验证。With the aid of eigenvalue calculations, the similarities and differences between two processing methods of input power signal in Linear Optimal Excitation Control (LOEC) applied to torque analysis method are studied in this paper. By applying the principle of selective modal analysis (SMA) method, this paper discovers and proves that the mathematic basis of torque analysis method is the approximate management of relevant eigenvalue function, and the application criterion is determined by the convergence of iterative process presented. The above conclusions are verified by case study.
