Modeling and Simulation in a Electrical Higher-Order RLC Tree Circuit Using Bond Graph/Simulink Approach

This paper applies Bond Graph (BG)/Simulink approach to establish the graphical model and simulation to observe the dynamic behavior in a higher-order tree circuit system. The physically significant energy elements Bond Graph model which can be converted to Simulink energy-based block diagram (SEBD) structure by our developed algorithm. The advantage of a SEBD model used to obtain accurately to investigate dynamic characteristics in the 21(superscript th)-order RLC tree circuit main system. The SEBD algorithm involved neither requires the somewhat complicated order reduction nor adopts the physically insignificant model reduction. The Matlab/Simulink simulation adopted in this paper uses a step function as input signal that join to the tree circuit main system, and three various kinds of load as subsystems which to link with circuit main system, and analyze the magnitudes of voltage and current state variable for every energy storage element. Results from the simulated analysis can then be used to predict the dynamic performance and time-domain trend analysis of the whole system.
