Abstract

This paper describes the lumped-parameter modeling, identification, and control of the payload temperature inside a high-altitude balloon gondola. Experimental methods for identifying the lumped thermal resistance and thermal capacitance at the launch-altitude and at high-altitude are described. Utilizing the identified values, both a pressureindependent model and a pressure-dependent model are formulated. With knowledge of the thermal resistance, a bang-off control system is sized to keep the payload temperature above a prescribed limit. Both of the closed-loop models are validated with recorded flight data.
