Aproximação polinomial da potência de regime do motor de combustão interna emulado por motores de indução trifásicos

Abstract

Improving the efficiency of hybrid electric vehicles (HEVs) is essential for advancing sustainable transportation. This study focuses on modeling the power supply of a combustion system in a scaled-down prototype that emulates the interaction between an internal combustion engine (ICE) and an electric generator of an HEV, using Hardware-in-the-Loop (HIL) technology. The adopted approach allows for emulating the energy generation system in steady-state operation, based on the rotation and torque difference between the machines, influenced by the angular movement of the throttle valve. In this context, a polynomial model was developed and validated using the Curve Fitting Toolbox in Matlab®, accurately capturing the relationships between power, speed, and valve opening. The proposed polynomial equation can be applied in ICE energy distribution strategies, reducing computational overhead and increasing operational efficiency. The quantitative results indicate that the polynomial approximation is suitable for practical prototype testing, opening new opportunities for developing more effective and sustainable energy solutions.
