论文摘要
本文通过利用Koopman操作员的光谱和灵敏度分析，提出了一类非线性动态系统的状态贡献因素。使用Koopman运算符的本征函数作为目标非线性系统，我们表明，模式和状态变量之间的相对贡献可以在线性方向上进行量化，在线性方面，该系统的非线性被考虑。提出的贡献因子应用于互连的AC/多末端直流电源系统的大信号模拟的数值分析。
This paper proposes a mode-in-state contribution factor for a class of nonlinear dynamical systems by utilizing spectral properties of the Koopman operator and sensitivity analysis. Using eigenfunctions of the Koopman operator for a target nonlinear system, we show that the relative contribution between modes and state variables can be quantified beyond a linear regime, where the nonlinearity of the system is taken into consideration. The proposed contribution factor is applied to the numerical analysis of large-signal simulations for an interconnected AC/multi-terminal DC power system.
