Concept
Pulse and Phase Width Modulation of both ENABLE (on/off) and PHASE (+/- polarity) can be optimized to control DC brush motor position.

The hypothesis of this project is that it should be possible to combine both Pulse and Phase modulation to provide measurably more efficient motor control than either method used by itself. The goal of this project is to determine the best methods for combining both Pulse and Phase modulation for brush DC motor control. Which method uses the least amount of power to hold a position? Which method provides smoother motion to and from the position? What is the best way to combine both methods to minimize the power required to hold a position and provide mobility?
