Modeling and Attitude Control of Cube Sat using Reaction Wheels

Attitude control system of a Cube Satellite has been modeled. Reaction wheels are used as an actuator. Two types of controllers have been designed for Attitude Control System (ACS). The two controllers are genetically tuned proportional integral derivative (PID), Modified proportional integral derivative (PI-D). The two controllers are compared without external disturbances. Also, the comparison takes into consideration the existence of sensor’s noise. The advantages and disadvantages of each controller are presented with the simulated results.
