Abstract

The invention relates to the technical field of radiation measurement, in particular to a solar radiation monitor in-orbit self-tuning method based on an extended response curve method, the self-turning method comprises the following steps: acquiring a temperature step response curve of a receiving cavity, and identifying a mathematical model of the receiving cavity; acquiring the sensitivity of the receiving cavity; establishing a relationship between the mathematical model parameters and PI controller parameters to obtain a first control strategy; establishing a relationship between the PI controller parameters and the sensitivity of the receiving cavity to obtain a second control strategy; and calculating the PI controller parameters according to the first control strategy, the second control strategy and a preset PI controller parameter information table. According to the method, the mathematical model of the receiving cavity is identified, the PI controller parameters are set according to the PI parameter information table, and when the working environment of the PI controller changes, the mathematical model of the receiving cavity is corrected, so that the environmental adaptability of the PI controller is improved, and the problem that the rapid measurement algorithm of the solar radiation monitor cannot be applied in orbit is solved.

Description

technical field [0001] 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. Background technique [0002] Climate change is one of the great challenges facing the world today, and the scientific community is committed to studying the mechanism of climate change. Solar radiation provides the vast majority of energy input to the Earth system and drives nearly every dynamic process in the Earth system. The Earth's energy balance is directly dependent on incoming and outgoing electromagnetic radiation. The influence of the sun on Earth's climate has received extensive attention. Since 1978, countries such as Europe and the United States have carried out measurements of total solar irradiance based on satellite platforms. Since then, a variety of radiometers have carried different satellite platforms successively, and obtained the total so...
