Abstract

The invention relates to an endocrine-algorithm-based intelligent plasma density control method for tokomaks. The method includes: using a high-speed data acquisition channel to acquire density information, applying hormone regulation algorithm of endocrine system to the parameter control for a PID (proportion integration differentiation) controller and the ultrashort feedback control, and using a pulse inflating mechanism to inflate a plasma chamber. The hormone regulation algorithm of endocrine system is applied to adjusting three control parameters, namely proportional gain, integration time and derivative time, of the PID controller, and accordingly controlling is higher in timeliness and robustness. The ultrashort feedback control is achieved by the ultrashort feedback mechanism of the neural endocrine system according to the change rate of PID control signals, so that control deviation is reduced to zero faster and system rapidity and stability are further increased. The endocrine-algorithm-based intelligent plasma density control method for tokomaks allows for real-time and stable control of plasma density for tokomak nuclear fusion devices, and is intelligent.

Description

Technical field [0001] The invention relates to the fields of biological intelligent control technology, high-speed data acquisition technology and magnetic confinement fusion, and mainly relates to an intelligent control method for plasma density of a tokamak device based on an endocrine algorithm. Background technique [0002] The tokamak device plasmaizes the fusion material through magnetic confinement, creates a plasma, and heats the plasma to a certain high temperature to make it close enough to cause a nuclear fusion reaction and release nuclear fusion energy. The current tokamak devices all control the rate of addition of nuclear fusion fuel (ie deuterium-tritium gas) and the amount of each addition, so that the nuclear fusion reaction proceeds continuously or rhythmically on a certain scale. The density of the gas in the nuclear fusion device is very low, only equivalent to one tens of thousands of the density of the gas under normal temperature and pressure. Therefore,...
