| Abstract: | In response to the high stability temperature control demand put forward by the gravitational wave detection Taiji 2 satellite, research on high resolution temperature measurement system and high stability thermal control technology was carried out, a multi stage damping thermal control design method was proposed, a multi stage damping state space mathematical model was established, and the heat transfer characteristics in the system were revealed. The method was verified by ground test on the core load of Taiji 2, and the test results showed that the temperature of key instruments in the core module met the index requirements. The noise analysis of the test results not only verifies the key technology of precision thermal control, but also proposes a new method about thermal noise analysis and suppression, which provides a theoretical analysis method and engineering reference basis for the subsequent spacecraft precision thermal control technology. |
