Summary on Grant Application Form |
|
Many rotor/magnetic bearing systems are subjected to disturbance inputs resulting in transient rotor vibration. Disturbance may arise from the normal operating environment of a machine or from fault conditions. The exact form of the disturbances may be uncertain, as are onset times and duration. A major problem with transient vibration is that a system may be driven into a highly reactive state from which damage may ensue. A machine that contains active elements offers the potential to be able to compensate for transient vibration and avoid failure. The broad aim of the project is to use wavelets for transient vibration control in active rotor/magnetic bearing systems. Control will be formulated in the wavelet coefficient domain to achieve rotor transient vibration attenuation whilst maintaining stable controller operation. Stability boundaries will be assessed in terms of the controller design parameters through extensive simulation studies. Transient vibration arising from direct rotor forcing, base motion, rotor/stator contacts, measurement error and fault conditions will be investigated. Control designs will be implemented in experimental facilities. The controllers will be derived from plant models obtained from finite element analyses and off-line measurements. A comparison will be made of the relative controller performance from vibration attenuation measurements.
