One of the goals of a hybrid electric vehicle design is to improve the overall performance of the vehicle by incorporating several different power sources in such a way as to maximize the energy usage. By combining the desirable characteristics of each of the components in the system, the vehicle becomes more efficient to operate. Energy storage systems such as batteries and ultra-capacitors can be used to supply or store energy from the system when needed. The primary power source in this model will be an internal combustion engine coupled with a permanent magnet synchronous generator. The purpose of this thesis is to analyze simulation models of the power management system and coordinate these power sources to supply the needed power to a brushless DC motor which acts as part of the propulsion system of a vehicle --Abstract, page iii
