Thanks for the reply!
The idea for the procedure came from both articles.
The first pointed to a resource 'Nonlinear Control Systems Analysis and Design' - Horacio J. Marquez where the variable gradient method is defined and how to determine the V(x) based on that gradient - step 2.
From the...
Thanks for the answer!
I found another article that gives a theorem for stability analysis of FLC.
I came up with the following steps:
1. write the longitudinal (short period and phugoid) and lateral (duch roll and spiral) modes equations;
2. for each of the 4 sets of equations, use the...
Hello,
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...
