Design of Finite Time Sliding Mode Control for Stable DC Bus and Current Tracking in a Multisource Hybrid Electric Vehicle

The increasing demand for clean and efficient transportation has shifted research focus towards hybrid electric vehicles. This study focuses on designing a nonlinear controller for a multisource hybrid electric vehicle comprising a fuel cell, battery, supercapacitor, and photovoltaic panels. DC converters act as an interface between sources and the DC bus. An FTSMC controller is designed and developed to ensure accurate current tracking for all sources and effective regulation of the DC bus voltage. The stability of the proposed controller is verified using Lyapunov stability analysis, and its performance is assessed using MATLAB/Simulink. The EUDC cycle has been used as a load profile for the proposed HEV. The results demonstrate fast and robust control performance under varying operating conditions, confirming the controller’s effectiveness for multisource HEV applications.
