Need to incorporate measured plant response into model

Hi all,

I have a measured component response ( http://www.mikejstein.com/Files/Random/response.png). Now, I'd like to come up with a FIR representation of this plant response to incorporate in a model. I'd also like to come up with a functional approximation to the measured data. I really don't know where to start with this one... any advice?

Thanks,

Mike

Hi Michael, One approach is to use System Identification Toolbox, which lets you create models from frequency-domain data. See this demo for more details: http://www.mathworks.com/products/sysid/demos.html?file=/products/demos/shipping/ident/iddemofr.html

What kind of data is it? You could try "impulseest" function in R2012a release which is an FIR estimator.
