摘　　要：针对磁悬浮轴承系统位移检测的特点,设计了一套以TMS320F2812 DSP为核心的磁悬浮轴承位移检测控制系统。详细介绍了电涡流位移传感器的工作原理,设计了磁悬浮轴承系统的数字控制器、位移信号调理电路等相关硬件电路,并对所设计的位移检测数字控制系统进行了软件实现,给出了主程序和中断子程序流程图,最后,对所设计的磁悬浮轴承位移检测数字控制系统进行了试验验证。Aiming at the characteristics of displacement detection of magnetic suspension system, a displacement detection and control system is designed based on TMS320F2812 DSP controller. The operating principle of the eddy current displacement sensor is introduced in detail, and the relevant hardware circuits are designed, such as digital controller, displacement signal conditioning circuits. The system is put into software realization, and the main program flow chart and the interruption subroutine flow chart are also given. Finally, the designed displacement detection digital control system for magnetic suspension system is verified by the experiment.
