Abstract:Another major contribution of this thesis work is the development of new approaches to achieve broad-band active vibration isolation with electrohydraulic actuation. Two new methods, the velocity-tracking approach and the position-tracking approach, are proposed and implemented in a custom-built multiple degree-of-freedom active vibration isolation testbed. These approaches circumvent the fundamental bandwidth limitations associated with traditional force-control approaches, and significantly improve vibration isolation performance achievable by force-control approaches. The effectiveness of the position-tracking approach to selectively isolate different vibration modes in multiple dimensional systems is also demonstrated through simulation studies.
