Abstract :
A dynamic controller is derived for a spacecraft with flexible appendages. The control aim is to design a control law that, using only attitude measures, allows for performing large angle manoeuvres. The approach is based on passivity concepts and the resulting controller ensures the asymptotic satisfaction of the control objectives and gives also estimates of the modal variables converging to the real values
