In this study, the algorithm was applied to a model of an unstable electrical system with a degree of 66 and reduced to degrees 8 and 15. Simulation results using Matlab showed that the HBT method was successful in reducing the order of the system and improved simulation time. The reduced-order system of degrees 8 or 15 can be used in place of the original system in applications in the time or frequency domain during analysis, design, simulation or implementation of electrical networks.

Ebook "Physical modeling in MATLAB® (Version 3.0.0)" presents the entire modeling process, including model selection, analysis, simulation, and validation. I explain this process in Chapter 1, and there are examples throughout the book. Simulation is an approach to modeling that uses computer programs to implement models and generate predictions. This book shows how simulations are used to run experiments, answer questions, and guide decision making.
