FUZZY AND ANN APPROACHES FOR PREDICTION OF RETAINED CAPACITY OF BACK UP POWER SOURCE IN GEO SPACECRAFTS

Abstract

Capacity of the batteries degrade (fade) with calendar life. Fuzzy logic and ANN models are developed to predict the retained capacity. The Developed models are compared and validated using statistical method and Bland Altman plot. Both Fuzzy and ANN models are able to predict the retained capacity more accurately within a test dataset and ANN model is recommended for extrapolation.
