This paper presents a study of model reduction techniques, as well as controller reduction via closed-loop considerations in designing robust tilt controllers to improve the curving performance of high-speed railway vehicles. The schemes make exclusive use of local practical signal measurements, i.e. sensors mounted on the current passenger coach. The fundamental problem related to straight-forward classical nulling-feedback control is presented, and the commercially used command-driven with precedence scheme is introduced. Simulation results and an appropriately defined tilt control system assessment method are employed for illustrating the efficacy of the reduced-order robust tilt controller.
