how to normalize worst case results (obtained with robuststab) within physical uncertainty boundaries?

Hi everyone,

I am new to this community and I hope to be of some help to you guys and also to receive some help for the current problem I am trying to solve.

I am using the robuststab command to perform a worst case analysis; some variables of my problem are defined with 'ureal' as for: A6 = ureal('A6',A6nom,'Perc',15); while others are defined as 'ultidyn' as for delta = ultidyn('delta',[1 1]);

I build my model and perform the stability analysis with robustab. The worst case I obtain is out of the physical uncertainty boundary I initially defined (so out of 15% uncertainty defined for A6, for instance). (maybe the main issue I have is that I don't know how to deal with worst case results of ultidyn...)

How can I scale this worst case to lay inside the physical boundaries I have defined (the obtained worst case is not real and I want to bring the solution back to the admissible boundaries of my problem)?

Do I need to scale the variables manually or there is a command to do that?

Thank you very much in advance for any help you can give me
