22 June 2006 Perturbation rejection control strategy for OWL
Author Affiliations +
The control system of the ESO 100m telescope (OWL) has to reject slow and fast perturbations in several subsystems. In this paper we focus on the wind rejection control strategies for two subsystems: the main axes and the segmented mirror. It is shown that facing the same disturbance the 2 control designs have to deal with completely different problems: control of a flexible SISO (Single input-Single output) system for the altitude axis versus a dynamically coupled MIMO (Multi input-Multi output) system for the segmented mirror. For both subsystems feasible solutions are given.
