Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I've designed a FLC controller for an UAV and I want to analyze its dynamic stability.

In all "Flight dynamics and control" books I've read, the analysis is based on transfer functions of the aircraft (and exemplified on a specific aircraft like Cessna 172) and of the pilot (human or automatic).

On the other hand, I've found an article that is using Lyapunov stability theorem to prove whether a FLC is stable or not.

1. Is there such a thing as "transfer function for fuzzy logic controllers"?

2. Is it possible to analyze the stability of an aircraft in the sense of Lyapunov stability?

3. Do you have any other ideas to analyze the dynamic stability of an FLC?

Thanks!
