Abstract: This paper describes the proportional integral (PI) control of hybrid squeeze film dampers (HSFDS) for active control of rotor vibrations. Recently it was shown that the automatically controlled ...

Abstract: This paper summarizes the development of hybrid squeeze film dampers (HSFDs) for active control of rotor vibrations. Previously, it was shown both theoretically and experimentally that HSFDs can ...

Abstract: This paper summarizes the modeling and control of hybrid squeeze film dampers (HSFDs) for active control of vibration of rotors exhibiting multiple modes. In a recent paper (El-Shafei and ...
