Abstract

The robust stabilization of the angular position of a spacecraft with dynamic elastic elements under dissipative properties is proposed. The control scheme is based on bang-bang control and linear output feedback. The former is based on minimum-time optimal control and the latter is designed with the invariant ellipsoid method. The control is achieved under uncertainty in the system and disturbances in the output measurements.
