Abstract

This thesis describes the development of the torque control algorithm for a Permanent Magnet Brushless DC (PM-BLDC) machine used as a starter/generator in a hybrid electric vehicle. A comparison of the different methodologies and concepts known for a starter/generator application is presented. It is followed by a presentation of the PMBLDC machine drive including the structure of the controller. The Proportional-Integral controller technique has been chosen for current or torque control for its ease of implementation in a DSP. The feasibility of using the PM-BLDC machine drive for a starter/generator application was first studied through simulation. The transition from thesimulation to the application itself was not seamless; the biggest challenges were dealing with noise and assumptions made within the model. On the other hand, the experiments proved that the concept is suitable for the starter/generator application. The fault tolerance and robustness of the starter/generator in the vehicle need to be investigated.
