提出了网络复频域分析的双边Laplace变换法,在证明恒值激励源的双边Laplace变换象函数的基础上,给出了动态元件的双边s域模型,阐明了网络换路前后拓扑结构不变的处理方法及响应求解过程。具体实例表明:该方法具有建模简单、分析方法通用、不必求解动态网络的初始状态亦可直接得到网络在复频域范围响应的特点。文中方法从网络建模角度对非因果系统转换为因果系统提供了一种新思路。
Bilateral Laplace transform of network complex frequency domain analysis is proposed. Based on the proof of the bilateral Laplace transform image function of constant excitation source, the bilateral s-domain model of dynamic element is given. The topology structure before and after the network is changed The processing method and response solving process. The example shows that this method has the advantages of simple modeling and general analysis method, and can directly obtain the network response in the complex frequency domain without solving the initial state of the dynamic network. The method in this article provides a new way of converting non-causal systems into causal systems from the perspective of network modeling.
