摘　　要：为使无轴承永磁同步电机(BPMSM)控制和调试更方便,设计了模块化的控制系统软件程序.在阐述BPMSM转子悬浮原理的基础上,给出其电磁转矩方程和悬浮力方程.在论述BPMSM数字控制系统功能框图的基础上,提出模块化设计的控制系统软件结构,并给出其各模块的具体实现方法.最后给出DSP中的2种临界资源管理机制,以确保整个软件系统的快速、稳定运行.搭建了BPMSM数字控制系统试验平台,对样机转子进行了悬浮试验研究.结果表明:采用模块化软件编程思想及相应的实现方法与管理机制,可以很好地实现BPMSM转矩控制、悬浮力控制与人机交互各部分控制功能,满足BPMSM的控制要求.该软件结构及其相应各实现方法与管理机制为无轴承永磁同步电机的控制奠定了基础.To control and debug the bearingless permanent magnet synchronous motor（BPMSM） conve-niently,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 ma-nagement 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 human-computer interaction can be implemented well by the modular software structure,implementing methods and management mechanisms.The software can meet the desires of BPMSM control.
