title: Matlab - find dominant poles programmatically
body: <p>I have a SISO system (in tf form) with 48 eigenvalues and I want to find the dominant poles (let's say to reduce it to a 1st or 2nd order). I need to know them to approximately calculate damping and bandwidth of my system. I would like not to rely on identification from time responses and I don't want to watch the pzmap (since I have to do it many times). Does anyone have an idea to solve it? Thanks in advance for help.</p>
