This paper proposes an attitude control of a satellite using a sliding mode control algorithm and a new design testbed. A testbed of the satellite system is designed and built to mimic the attitude control while the satellite is orbiting on a 2D platform. The system consists of the satellite model, the flat table, and the counterbalance mass. The satellite model can be divided into two sections, the top section and the bottom section which can be rotated independently. The bottom section was installed with the flat air bearing to reduce the friction between the satellite model and the flat table, the link between the satellite model and the counterbalance mass to simulate the centripetal force for the satellite orbiting, and the IMU to determine the angle of rotation during the orbit. The top section has the IMU to determine the actual heading of the satellite by calculating the relative angle with the IMU in bottom section, and two cold gas thrusters to control the heading of the satellite. The dynamics of the system is derived based on cold gas thrusters as the actuators and combined with the dynamics of the attitude of the satellite. The sliding mode controller is proposed to control the duty cycle of the on-off cold gas thrusters. The control performance is evaluated from both of simulation and experimental results.
