Investigation on Digital Integrated Controller of Active Magnetic Bearings

A digital integrated controller of active magnetic bearing was developed based on digital signal processor(TMS320F28335  DSP). The controller could  take the place of the general displacement controller and some parts of the power amplifier.The corresponding control algorithm was programmed,and the static and dynamic performances of the controller were  investigated by experiments.The digital integrated controller was also introduced into five degree-of-freedom active magnetic bearing flexible rotor system,and the system could operate at high rotation speeds safely. The results show that digital integrated method possesses low cost, transportability,high  reliability,small size,and is helpful to optimize the performance of electronic control system.
