How to initialize the Hammerstein model linear block and avoiding that the nlhw function transform the linear block to polynomial form ?
Hi.
I am trying to estiamte a Hammerstein Model. I have a state representation of the linear block to generate the Hammerstein model, however for some reason the idnlhw function convert the state representation that I have to polynomial form. The above should not be a problem, but the poles of linear block are close together due to the slow dynamcis of my system. From what i read in this post https://la.mathworks.com/help/control/ug/sensitivity-of-multiple-roots.html closelied space poles are very sensitivy to model transformaiton from state space to polynomial represntation.
The above becomes problematic because I want to program this model in a 32-bit microncontroller but this pole sensitivy changes the value of my poles when I convert them to single precision.
How can I solve this issue.Hi.
