介绍了DIII-D托卡马克等离子体控制系统的软件结构。该系统通过在一个或多个数字计算机上真实的实时执行的软件来实现控制功能。该软件被组织成一个层次结构，允许新的控制功能，需要支持DIII-D实验程序被很容易地添加，而不影响以前实施的功能。这也允许软件是便携式的，以便为其他应用创建控制系统。托卡马克操作员使用基于X窗口的接口来指定托卡马克放电的时间演化。该界面为操作员提供高级视图，减少了对控制系统操作的详细知识的需要。提供了响应于在真实的时间中检测到的事件而异步改变到替代放电时间演变。通过离线测试，可以利用基于软件的托卡马克模拟器的质量控制得到加强。
The software structure of the plasma control system in use on the DIII-D tokamak experiment is described. This system implements control functions through software executing in real time on one or more digital computers. The software is organized into a hierarchy that allows new control functions needed to support the DIII-D experimental program to be added easily without affecting previously implemented functions. This also allows the software to be portable in order to create control systems for other applications. The tokamak operator uses an X-windows based interface to specify the time evolution of a tokamak discharge. The interface provides a high level view for the operator that reduces the need for detailed knowledge of the control system operation. There is provision for an asynchronous change to an alternate discharge time evolution in response to an event that is detected in real time. Quality control is enhanced through off-line testing that can make use of software-based tokamak simulators.
