Abstract
The application discloses a kind of ECRH system millimeter wave power monitoring and compensation method and system, belong to magnetic confinement nuclear fusion plasma heating and microwave measurement technical field;The application is by constructing energy integral constraint under time delay alignment offline training data set, trains millimeter wave power thermal drift compensation model with detection voltage and detector temperature as input;After model quantization is low bit model, it is deployed in edge control platform, forms the double-rate compensation architecture of " slow loop reasoning-fast loop execution ": slow loop periodically reasons dynamic compensation coefficient, fast loop carries out real-time linear compensation to high-speed detection voltage with this coefficient and executes microsecond level interlock protection;The application takes into account the high-speed response of diode detector and the high accuracy of calorimetry, can realize high-precision, low-latency, high-robustness power monitoring and interlock protection under long-pulse, high-power conditions, significantly improve the safety of fusion device operation and the accuracy of physical analysis.
