This article presents a case study of an application of four optimal ℋ ∞ controller synthesis methods (mixed sensitivity, four-block design, loop shaping and mixed-sensitivity II) to the THSA control problem. The designed controllers are then experimentally tested on the THSA test rig and the design techniques are compared with respect to the performance of their controllers and the ease of their implementation.en0743-1546201048634868IEEETechnikIngenieurwissenschaftenJournal Article10.1109/CDC.2010.5716948Other
