摘要：

Control of a magnetic bearing device is addressed by parameter varying control. Within the structure of decentralized PID controllers we compare linear interpolation and switching strategies with and without hysteresis. Piecewise LPV decentralized PID controllers are found to be an interesting alternative. Our method exploits the possibility to pre-compute for every parameter value an H-infinity optimal decentralized PID controller, and to use this ideal model to construct practical scheduled controllers with an acceptable H-infinity performance.
