Abstract :
A backstepping adaptive attitude tracking controller for flexible spacecraft with collocated sensor and actuator pairs is studied. Firstly, spacecraft´s angular velocity is selected as virtual control vector, and a constant coefficient feedback intermediate control law is designed to stabilize the spacecraft attitude quaternion error equations; then, via backstepping control algorithm, an adaptive controller is acquired. Finally, numerical simulation results demonstrate the efficiency of the controller.
