Interleaved Boost Converter Control Technique Improvements for Fuel Cell Electric Vehicles

This study presents some control technique improvements for an interleaved boost converter for fuel cell electric vehicles. Self-tuning PI controller and an adaptive PI controller using fuzzy logic technique have been designed and developed to improve the voltage tracking accuracy. Several scenarios and tests including load disturbances were carried out to evaluate and to compare the performance of the improved controllers with the conventional one. The obtained results show a superior and high performance of the improved techniques compared to the fixed gains PI controller without adding any extra sensors.
