Abstract

The invention relates to the technical field of radiation measurement, in particular to an on-orbit self-tuning method for a solar radiation monitor based on an extended response curve method. The method includes obtaining a temperature step response curve of a receiving cavity and identifying a mathematical model of the receiving cavity; obtaining Sensitivity of the receiving cavity; establish the relationship between the mathematical model parameters and the PI controller parameters to obtain the first control strategy; establish the relationship between the PI controller parameters and the sensitivity of the receiving cavity to obtain the second control strategy; according to the The first control strategy, the second control strategy and the preset PI controller parameter information table are used to calculate the PI controller parameters. The method identifies the mathematical model of the receiving cavity and adjusts the parameters of the PI controller according to the PI parameter information table. When the working environment of the PI controller changes, the mathematical model of the receiving cavity is corrected to improve the environmental adaptability of the PI controller and solve the solar problem The problem that the rapid measurement algorithm of the radiation monitor cannot be applied in orbit.

Description

Technical field [0001] The present invention relates to the field of radiation metering, and more particularly to a solar radiation monitor based on the expansion response curve method in rail self-tuning method. Background technique [0002] Climate change is one of the huge challenges in the world today, and the scientific community is committed to studying the mechanism of climate change. Sun radiation provides vast majority of energy inputs for earth systems, almost driven each dynamic process in the earth system. Earth energy balance directly depends on the electromagnetic radiation of the input and output. The impact of the sun on the Earth's climate has been widely concerned. Since 1978, Europe, US and other countries launched the sun-based total radiation measurement based on the satellite platform. Since then, a variety of radiometers have been equipped with different satellite platforms, and the sun radiation observatory observation data in nearly 40 years is obtained. ...
