AUTOMATIC CONTROL SYSTEM FOR THE SUPPLY OF PRODUCER AND PROCESS GASES IN VARIOUS MODES OF OPERATION OF A TOKAMAK-TYPE PLANT Russian patent published in 2023 - IPC G21B1/00 

FIELD: controlled thermonuclear fusion.

SUBSTANCE: means for automated control of production processes in the field of controlled thermonuclear fusion implemented on plants of the tokamak type. The automatic control system for the inlet of producer and process gases in various modes of operation of a tokamak-type plant consists of a vacuum chamber, which is connected via a channel for controlling the glow discharge current in the process gas to a unit of the system for cleaning the chamber with a glow discharge, which is connected via a digital channel for transmitting the gas pressure setpoint to a mismatch signal calculation unit, through the pressure control channel in the preliminary gas purge mode with the producer gas pressure control system unit before breakdown. The mismatch signal calculation unit and the universal controller are interconnected by a digital mismatch signal transmission channel and form a multipurpose real-time controller. Moreover, a multipurpose real-time controller, a digital-to-analog converter unit, an analog-to-digital converter unit and a reflective memory module unit form a crate with a controller and interfaces.

EFFECT: implementation of an automatic process for controlling the inlet of producer and process gases into the installation in various operating modes of the tokamak by cascade control of piezoelectric valves using a controller with a multipurpose regulator.
