Title:Hydraulic Switching Control of Resonant DrivesAuthor(s):Helmut Kogler, Rudolf ScheidlAbstract:In this paper the concept of a hydraulic buck converter driving a load at resonance is discussed. The performance is compared with conventional proportional control and proportional control of a resonant drive. As an example the oscillation drive for a mould of a continuous steel slab caster is taken to benchmark the concept. Such moulds have typically a weight of 20 tons and are oscillated at frequencies up to 5 Hz and a stroke of 7 mm. It is shown that a good performance and substantial energy savings compared to conventional hydraulic resistance control can be achieved with this concept.Booktitle:Proceedings of the 12th Mechatronics Forum Biennial International Conference, June 28-30, 2010, Swiss Federal Institute of Technology, ETH Zurich, SwitzerlandPage Reference:page 97-102, 6 page(s)Publishing:2010
