Hi everybody, I need to derive a mathematical description for non-linear torque-speed curve for DC servo motor.
I'm not sure how to approach the problem and I was wondering if anybody can recommend some literature (books, articles, etc.). What do I need to take into consideration? How to model such a system? Does it involve modelling the control (PID loop and PWM).
I understand it's not an easy task but it would help me a lot if someone could push me into the right direction.
Regards, Pawel
