Hello, I need to build an uncertain idpoly model. I have the FIR coefficients (e.g. B(z)=[0 1 2 3 2 1]) and the sampling time (e.g. Ts=1 s), then I build a idpoly model according to the MATLAB help:
sys=idpoly(,[0 1 2 3 2 1],,,,,1)
Now the question: I also have an uncertainty in each FIR coefficient which is expressed in standard deviation: std=[0 1e-3 2e-3 3e-3 2e-3 1e-3]. How can I incorporate this knowledge in the idpoly model?
