提出了一种求解复杂线性动态系统的频率平均框架。值得注意的是,虽然中频区域通常非常具有挑战性,但从低频到中频和高频范围的平稳过渡是可能的,现在可以在一个框架内考虑所有范围。在时域中的频率平均的解释,并解释说,平均值可以非常有效地评估系统解决方案。
A frequency averaging framework is proposed for the solution of complex linear dynamic systems. It is remarkable that, while the mid-frequency region is usually very challenging, a smooth transition from low- through mid- and high-frequency ranges is possible and all ranges can now be considered in a single framework. An interpretation of the frequency averaging in the time domain is presented and it is explained that the average may be evaluated very efficiently in terms of system solutions.
