Programmable control of the inductive electric field enables advanced operations of reversed-field pinch (RFP) plasmas in the Madison Symmetric Torus (MST) device and further develops the technical basis for ohmically heated fusion RFP plasmas. MST’s poloidal and toroidal magnetic fields ( B p and B t ) can be sourced by programmable power supplies (PPSs) based on integrated-gate bipolar transistors (IGBT). In order to provide real-time simultaneous control of both B p and B t circuits, a time-independent integrated model is developed. The actuators considered for the control are the B p and B t primary currents produced by the PPSs. The control system goal will be tracking two particular demand quantities that can be measured at the plasma surface ( r = a ): the plasma current, I p ∼ B p ( a ), and the RFP reversal paramet...

使用先进的可编程电源同时对MST上的环形磁场和等离子体电流进行反馈控制

感应电场的可编程控制使麦迪逊对称圆环（MST）装置中的反向场收缩（RFP）等离子体能够进行高级操作，并进一步发展了欧姆加热聚变RFP等离子体的技术基础。MST的极性和环形磁场（B p和B t）可以由基于集成栅双极晶体管（IGBT）的可编程电源（PPS）提供。为了提供对B p和B t电路的实时同时控制，开发了与时间无关的集成模型。考虑用于控制的执行器是由PPS产生的B p和B t初级电流。控制系统的目标将是跟踪可在等离子表面测量的两个特定需求量（r = a）：等离子电流I p〜B p（a）和RFP反转参数...
