The speed loop consists in a speed regulation loop with the PID corrector.
We will further explain how to adjust the coefficients KP and KI. The KD coefficient is present in
the regulation loop but not used.
As previously shown, the KP coefficient is used to regulate the motor response time. First time
set KI and KD to ‘0’. Try different values of KP to get a correct motor response time.

If the response time is too slow, increase KP gain.
If the response time is quick, but motor speed is unstable, decrease KP gain.

KI parameter is used to cancel the static error. Leave the KP coefficient unchanged and set the
KI parameter.

If the error is still different from zero increase KI gain.
If the error is cancelled but oscillations appears, decrease KI gain.
