Fuzzy Modelling of Zero-pressure Balloon Ascent

• Zero-pressure balloon ascent prediction is a critical issue for Swedish Space Corporation(SSC) as targeted test ights are important part of SSC activities. This paper introducesa data-driven approach for estimating the balloon ascent. An output-constrained fuzzylogic approach is applied to the zero-pressure balloon data set from the past 10 years fromEsrange Space Center and rules are formulated that can express the balloon ascent. Theserules are veried by performing a root mean square analysis of estimated ascent againstthe real ascent trajectory. The result shows that the proposed fuzzy model is reliable andis able to estimate the balloon ascent with an acceptable accuracy.
