| PID regulator for speed |

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. |

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. |
