Power transfer function modeling method and application of it in energetic systems

摘要：

Bond graph is an effective modelling method based on power energy conversation,yet,the derivation of state function and simulation by Matlab/Simulink from bond graph model are relatively complex.In this paper,a novel modelling: power transfer function method is proposed.It utilizes bond graph effort,flow arguments and defines new conventions including basic element,block,branch point,forward sum point and feedback sum point to construct the total system model.The modelling steps of power transfer function are illustrated in detailed.Comparing with bond graph model,the simulation results of the examples from electric,hydraulic and mechanic domain prove the validity of proposed method.The power transfer function model is more visual and more convenient for obtaining systems’ transfer function.
