AbstractThe recent progress of the poloidal field control system of the HT-7 super-conducting Tokamak is presented. The distributed control system (DCS) was implemented on the poloidal field power supplies (PFPS) in 1998. The successful development of the new PFPS trigger system allowed the control cycle of the PF power supplies to reach 1–1.2 ms. The response speed of the control system was improved by ten times with reference to the former system. Secondly, based on software de-coupling of plasma equilibrium parameters, a multivariable feedback control scheme was implemented. Thirdly, the efficiency of HT-7 experiment operation was greatly improved by realizing the discharge experiment database of HT-7.
HT-7超导托卡马克极向场控制系统的最新进展。1998年，在极向场电源（PFPS）上实现了分布式控制系统（DCS）。新型PFPS触发系统的成功研制使极向场电源的控制周期达到了1–1.2 ms。与原有系统相比，控制系统的响应速度提高了十倍。其次，基于等离子体平衡参数的软件解耦，实现了多变量反馈控制方案。第三，通过实现HT-7放电实验数据库，大大提高了HT-7实验运行的效率。
