In this paper, a series of results related to the decoupling of the 10m diameter Grantecan’s primary mirror dynamics and its influence on the design of a controller for the mirror are presented. Firstly, an algebraic approach of the decoupling method, together with its general lines are shown. Some modifications of this procedure with respect to the way it was originally proposed with the aim of its simplification and improvement are also presented. Finally, a discussion about the design of a robust H-infinity controller for any of the SISO subsystems obtained after the decoupling and the corresponding results is carried out.
