Based on configuration and producing magnetic suspension forces of permanent magnet biased radialaxial hybrid magnetic bearing(HMB),the principle of control system on 3 degrees of freedom is expounded. The hardware of a digital control system based on a flxed-polnt digital signal processor TMS320F240, as well as software,is discussed. The control system of HMB is also simulated and tested. The research shows that the digital control system based on TMS320F240 can meet the requirements of magnetic bearing system.
