Hi everyone, in the last times, I'm really interested in controls engineering, and I wanted toknow how to find transfer functions of devices, or systems in the real world, let me explain better, for example, in my house i have various dc motors, and stepper motors, since i want to make an automatic control of the velocity, i'm blocked since i don't know the trasfer function of the motor... how can i proceed ? How can i find the transfer function of this motor ?(adsbygoogle = window.adsbygoogle || []).push({});

And in general how do i find a transfer function of a system, without knowing the matrixes A,B,C,D ?
