Abstract :
The paper deals with trajectory tracking for a rigid spacecraft under parameter uncertainties. This problem can be formulated as a structurally stable regulation problem. The reference inputs are generated by an autonomous system, the so-called exosystem. The solution of this problem entails the solution of the regulation equations, while the fulfillment of the robust requirement implies the immersion of the exosystem into observable system. Such an immersion allows all the possible steady-state inputs to be generated for the admissible values of the system parameters.
