Buck-Boost Converter with Fractional Control for Electric Vehicles

Abstract

In this paper, non-integer order control is applied

to improve the performance of a buck-boost dc-dc power

converter with ultracapacitor based on state feedback

techniques. The approach is based on stabilization in the

Lyapunov's sense for linear rational-order systems. The

ultracapacitor can overcome the classical problems of energy

losses due to the use of batteries, giving more accuracy,

autonomy and efficiency to the electrical vehicles.
