In this paper, different control methods have been investigated for an earth observation satellite with push broom imaging. In pushbroom Imaging scan method, the satellite should be able to follow a certain path. Forward Motion Control method has been used to improve image quality. Due to the need for fine pointing and mild attitude maneuvers, reaction wheels are chosen as the control actuator. In this paper, PID, Fuzzy and extended LQR controllers is designed for a nonlinear model of a satellite. Research results show that controller with PID Quaternion feedback has average precision with less computation. LQR controller with the extension of the cost function has the best tracking accuracy. Fuzzy controller generates Minimum control torque in comparison others.
