摘　　要：通过对交流伺服控制系统进行研究,成功将UC/OS-II实时多任务操作系统移植到STM32微控制器上,设计了一种基于STM32的实时控制系统,使得标定平台能够满足海流传感器检测性能要求。在伺服电机控制方面采用开环和闭环控制相结合的方式,不仅提高了平台的定位精度,还减轻了处理器的运算压力,提高了软件的实时性;上位机采用基于Lab VIEW的界面设计,直观监测标定平台的运行状态,并后台存储重要的数据信息。通过实验验证该控制系统满足标定平台速度稳定、定位精度高和低速运行的要求。Through the study of AC servo control system, successfully transplanted the UC/OS-II Real-time multitasking operating system to the STM32 micro-controller, a real-time control system based on STM32 was designed, which enabled the calibration platform to meet the requirements of current sensor performance. In terms of the servo motor control, the combination of an opened loop and closed loop control mode was adopted, not only improved the positioning precision of the platform, but also reduced the pressure of the processor＇s operation so as to improve real-time performance of the software. PC interface was designed based on Labview to make the calibration platform running condition monitoring intuitive, and stored important data information in the background. Experiments vali- date that this control system meets the requirements of calibration platform of speed stability, high positioning accuracy and lower speed operation, and etc.
