PID regulator for speed

(1/3) > >>

nForce:
Hello,

I would like to create a PID regulator where the input is speed and the output is torque. I know how a PID regulator looks like, I just want to know what kind of block (physical relation) I add such that I adequate convert from speed to torque.

Thank you.

Kleinstein:
Depending on the system driven with the torque, the system could be more integrating (if the kinetic energy is important) or more proportional if in a a more friction dominated range.

nForce:
@Kleinstein are you talking about tuning the PID regulator?

Now I have a PID regulator where we have input speed and at the end we sum the speed signals which come from P, I and D. But I can't just connect this sum with the output where we have torque. The relation from physics is P = T*RPM. But power is changing.

Yansi:
Connect it together and stop inventing why it can't be done!



And btw, the output of the speed regulator is not torque, but CURRENT instead. You can't regulate torque directly.

nForce:
Yansi, this is great but I want to know what is inside "Rw" block? How do we get from w_ref to I_ref?

Thanks, again.
