چکیده
* Address all correspondence to this author. ABSTRACT In this paper, a configuration of electric energy storage system for Hybrid Electric Vehicles has been proposed that consists of a small battery and ultracapacitor pack coupled to the vehicle bus through dc-dc converters. The entire system, together with necessary power electronics pack, has been modeled and a Model Predictive Controller (MPC) has been designed for the purpose of power management of the linearized system. This controller has been simulated with the nonlinear plant for charging and discharging current profiles and is shown to be working well around the equilibrium point of the plant. Results show the effectiveness of this approach in keeping the battery current small and steady during fast transients and peak load conditions.
