How to extract state for uncertain system for static controller?

I have uncertain system of thrid order described by transfer function. There are two uncertain parameters. How to extract state of the uncertain plant in order to connect it to static centroller or to use with programatic tuning (e.g. systune)?

Matlab generates uncertain system for the third order plant with two uncertain parameters of order 10.

Hi Wojciech,

To extract the state-space representation of an uncertain system described by a transfer function, you can use the uss (uncertain state-space) function in MATLAB's Control System Toolbox. This function converts a transfer function with uncertain parameters into an uncertain state-space representation.

You can refer to the following document to have a better understanding on uss function:

Uncertain state-space model - MATLAB (mathworks.com)

I hope this helps
