Analytical Feedback Design via Interpolation Approach for the Strong Stabilization of a Magnetic Bearing System
In this paper, a stable controller has been designed via an interpolation approach to stabilize an open-loop unstable MBC500 magnetic bearing system. An 8th-order model of the MBC500 magnetic bearing system was identified from the collected frequency response data. Since there are resonant modes that can threaten the stability of the closedloop system, notch filters are employed to help to secure stability. The controller has been designed on the basis of a reduced 2nd-order unstable model. The performance of the controller has been tested via simulation and compared with that of a conventional lead compensator. The controller designed via the interpolation approach has also been coded in C and implemented in real time on a Digital Signal Processor (DSP) card. Both simulation and implementation results show that the controller designed via the interpolation approach is superior in both closed-loop step responses and disturbance rejection.
