A Field Oriented control scheme for a BLDC (Brush Less Direct Current) motor is presented. The motor is used for attitude control of 3U sized Pico satellite by exchanging angular momentum with the rigid body. Compared to the conventional control schemes which give performance limitations, with FOC a better dynamic performance can be achieved, even the algorithm introduce more complex mathematical transformations in order to decouple the torque generation. The algorithm itself is implemented directly in the hardware and with the mathematical processing power of modern micro controllers such advanced control algorithms are easily implemented. Computer simulation is presented to verify the control strategy.
