This paper presents test results from the application of Adaptive Vibration Control (AVC) to a magnetic bearing equipped 6-stage hydrogen process compressor which operates at 20.6 MPa (3000 psi). This application represents the first time AVC has been demonstrated on a fully functional industrial machine. The results demonstrate the reduction in vibration levels possible with AVC operating in each of the two vibration control modes: synchronous position reduction which reduces the synchronous displacement of the shaft as measured at the bearing and synchronous current reduction which reduces the synchronous control effort by the bearings, allowing the shaft to rotate about its inertial center. A discussion is also included on future developments planned for AVC.
