Abstract: PURPOSE: A maneuverability and controllability improvement method is provided to improve the attitude maneuver performance of a satellite by simultaneously applying a reaction wheel-based and thruster-based attitude controller when a part of the reaction wheel is out of order. CONSTITUTION: A thruster-based attitude controller(110) controls the drive of the thruster loaded in a satellite. A reaction wheel-based attitude controller(120) controls the drive of the reaction wheel of a satellite. A satellite dynamic mechanics model(130) diversifies the attitude of a satellite. In a satellite, a plurality of reaction wheels are included. A reaction wheel speed controller(121) produces a reaction wheel torque by using an input value from the reaction wheel-based attitude controller. A reaction wheel model(122) produces the angular momentum and the second torque of a reaction wheel by using inputted reaction wheel torque. A summer(103) sums a first torque calculating from a thruster model and a second torque calculating from the reaction wheel model.
