Hi,

I have a second order undamped system 1/(s^2 + w^2), where w is the electrical speed of the motor.

Any tips how can I control this transfer function? Can I use the PI controller?

Thanks.

 

You have given the second order response of your final operator.

To discuss control of a motor you need to define what type of motor: induction, synchronous, variable speed AC, DC, etc. Then you also need to define the response of your sensor (presumed RPM), and finally that of the process you are trying to regulate...
