Enhancement of the Satellite Attitude Control Using Optimal Regulator Scheme

Mohsen Gol Zardian, Hishamuddin Bin Jamaluddin


Accuracy of satellite control for space investigation has priority during its mission. This study aims to design a controller for the satellite attitude control which carries scientific sensor package. The modeling of the satellite with its electronic device is carried out in order to capture the states of systems then the appropriate controller strategy is applied to keep the satellite at the fixed value. In addition, to satisfy the design characteristics two control schemes in comparative manner are discussed namely, state feed-back controller and linear quadratic regulator (LQR). The results show LQR helps satellite to follow its reference signal along with desired overshoot and settling time.
