Abstract：To control and debug the bearingless permanent magnet synchronous motor (BPMSM) conveniently, a modular digital control system software program was designed. Based on rotor suspension principle, the electromagnetic torque equation and radial suspension force equation of BPMSM were introduced. According to the functional block diagram of BPMSM control system, the modularization configuration of control system software and the realizing methods of its various parts were provided. The management mechanisms of two kinds of critical resource in DSP were proposed to ensure swiftness and stability of the control system. A digital control system experimental platform of BPMSM prototype was built to study the rotor suspension performance. The results show that all functions of BPMSM torque control, suspension control and humancomputer interaction can be implemented well by the modular software structure, implementing methods and management mechanisms. The software can meet the desires of BPMSM control.
