摘　　要：从任务执行时间和实时性两个方面分析了基于Windows与VxWorks双操作系统的HT-7超导托卡马克装置上等离子体密度反馈控制系统(DFCS)的特点,并和基于Windows与Linux下的系统进行了比较。结果表明:基于Windows与VxWroks双操作系统的DFCS具有更好的实时性、更为精确的控制效果以及更加稳定的控制过程。From the duration of the task and real time capability, the fundamental performance of the density feedback control system (DFCS) in HT-7 superconducting Tokamak equipment was analyzed. The system based on Windows and VxWorks was compared with that based on Windows and Linux. The results show that the DFCS based on Windows and VxWorks has a better real time capability, a better control effect and a more steady control process.
