Real-time predicting the thermal state of the electronic unit by analyzing trends in the built-in sensors readings

Abstract

The development of an integrated system for the monitoring and control of thermal operation modes of a spacecraft electronic module is being continuing. For physical experiments, a laboratory test bench was created. The test bench simulates the operating conditions for the electronic module close to the on-board spacecraft conditions. In [1], we construct a classifier which reliably determines a stationary operation mode of the simulator. Once an operation mode of the electronic module has been changed, the thermal field changes as well. In this paper we propose the approach to predict the temperature of the steady state for each sensor in a still unstable system.The development of an integrated system for the monitoring and control of thermal operation modes of a spacecraft electronic module is being continuing.
