Abstract:

This study examines the integration of a supercapacitor-based multilevel inverter within a traction control system, with a focus on its operational control strategies. A combined model incorporating traction control dynamics and forecasting of power generation from the supercapacitor is developed to optimize inverter operation and support real-time energy scheduling. The study introduces a droop control method specifically designed for power electronic converters interfaced with battery storage, thereby enhancing voltage regulation and load sharing in dynamic environments. Simulation models are created using LT Spice/ Simulink to evaluate three configurations: an open-loop super capacitor system, a closed-loop system using PID control, and a hybrid system combining super capacitors with a PID-controlled multilevel inverter. Comparative analysis of these models reveals that the PID-based inverter system significantly outperforms the others in terms of response speed, voltage regulation, and system stability. The closed-loop control enables more accurate handling of transient conditions, reducing voltage sag and improving current regulation. Furthermore, the system demonstrates reduced hardware complexity, offering a compact and cost-effective solution suitable for traction applications. By leveraging the rapid charge-discharge characteristics of super capacitors along with the fine-tuned control capabilities of PID algorithms, the proposed system ensures reliable and efficient traction performance under variable load conditions.
