Control of Surge in Centrifugal Compressors by Active Magnetic Bearings

All three authors of this book are affiliated with the Rotating Machinery and Controls (ROMAC) laboratory. Dr. Paul E. Allaire is the director, Dr. Zongli Lin is a faculty member and Yoon Se Young is a graduate research assistant of the laboratory. The ROMAC Industrial Program supports cooperative research efforts conducted by faculty, staff, and students in the Mechanical and Aerospace Engineering Department and the Electrical Engineering Department at the University of Virginia. The ROMAC Industrial Program emphasizes theoretical and experimental research in areas such as rotordynamics, turbomachinery, magnetic bearings, and the application of automatic controls to the dynamics of rotating machinery. Current ROMAC industrial partners include many of the major compressor manufacturers and end-users in the world, including Kobelco, Industrial Technology Research Institute (ITRI) of Taiwan, Cameron Compressors, Dresser-Rand, Siemens, UTC, Rolls Royce, Turbo Care, Solar Turbines, and Elliott Compressors.
