Abstract:

In order to meet extremely requirements of real-time responds for control system of poloidal field power supply, the real-time Linux is choosed as the system platform, an opened-source code, extensible Eclipse based on C/C++ as development tool, and a master control system for poloidal field power supply is designed. This design realized real-time communication and real-time control with 12 sets local controllers of poloidal field power supply system in a control cycle (1ms). A feasibility solution about some key problems of the main controller was presented, such as high-speed communication and real-time control, stability and reliability and so on. The design is evaluated and tested, and it completely meets the real-time requirements of control system for the poloidal field power supply.

Key words: Poloidal field power supply, Main controller, Real-time Linux, Timer, Real-time control, High-speed communication

摘要：

为了满足极向场电源控制系统严苛的实时响应的要求，选择实时Linux系统作为系统平台，采用一个开放源代码的、基于C/C++的Eclipse可扩展的开发平台作为开发工具，完成极向场电源主控制系统的设计，实现了在一个控制周期内(1ms)对极向场电源系统的12套本地控制器的实时通信和实时控制。对极向场电源主控制系统的高速通信和实时控制、稳定可靠等关键问题给出了可行的实践性的解决方法。经实验测试，该设计运行稳定，能满足极向场电源控制系统的实时需求。
