Abstract

Aframework based on the gap metric is proposed to validate mathematical models of aircraft dynamics using flight data. The approach derives stability margin requirements, and hence is ideally suited to support model-based design and certification of flight control algorithms. This paper shows that the gap metric is an extension of the Theil inequality coefficient: A widely used metric for model validation. The approach is demonstrated on a case study with a small unmanned aircraft.
