The aim of this paper is to propose two procedures for the design of a robust discrete time controller for the flexible transmission system of Landau et al. (Proc. Europ. Control Conf., Rome, Sept. 1995). The procedures are based on discrete time versions of the two degree offreedom (TDF) methods of Limebeer et al. (Automatica, 29(1), 1993, 157–168) for designing robust controllers. The first method involves designing the feedback controller and prefilter in a single stage using H optimisation. It is this approach that is evaluated on the flexible transmission problem. The second approach involves two stages in which both the feedback controller and prefilter are optimised separately.
