Energy based control of hydraulic actuators in steel rolling mills

Research output: Contribution to journalConference articlepeer-review


This contribution deals with an energy based controller design for hydraulic actuators. Equilibrium thermodynamics is used in order to establish the energy relations for physical systems with mass flow across their boundaries. A double acting hydraulic ram is used as an application example. FUrther, an energy based controller is derived for this multi-input-multi-output system. Finally, industrial measurements from a steel rolling mill which demonstrate the implemented control law will be presented.
