“…Works related to control design for active TPJBs can be found in [20,21,22,23,24,25,26]. In the industry, the majority of the critical machines feature flexible rotors which make them worth analysing when supported by active TPJBs, in the same way as when they are supported by conventional TPJBs [27,28,29,30,31,32]. In rotating systems, the bearing dynamic properties heavily influence the whole system dynamics because they provide the main source of energy dissipation through the lubricating fluid film.…”
