How can I find the phase programatically, of an Uncertainty plot like this one? This transfer function is build using the Robust Controls toolbox.
Eg I'd like to read at what frequency range, the phase drops to (say) -45 degrees.
If this was a normal bode of a single SISO model, it'd be easy: do a bodeplot() and read out phase and magnitude data, and/or use margin().
But this is an uncertain model range. I don't know how to read out the phase data, much less its bounds.
Does anyone know how to get phase data of Uncertain models?
a = ureal('a', 1, 'percent', 50);
