摘要

In this paper, a satellite health assessment model based on prediction data is proposed to research on the health assessm ent of the components of the satellite department in the future. Firstly select the temperature, voltage, and current telemetry para meters that can reflect the health of the component, use the CEE MDAN-PSO-ELM model to make single-step, three-step, and five -step predictions respectively, and then integrate the score which from the non-dimensional dimensionless model and the entropy weight method to get 'health', finally use the telemetry data fro m satellite to experiment. The experimental results show that single-step, three-step and five-step predictions can all accurately pr edict the change trend of the 'health' of the future state assessme nt of the component, and the mean square error (MSE) index of s ingle-step prediction is only 0.0049, which can evaluate the future status of the components.
