7.4.1.1Speedobserver
The speed observer is a simple model of the path with motor current as input, as
estimation of load torque and feedback of the estimated error from encoder position
for speed control. The observer generates an estimation of motor speed that is used
as an alternative to the measured, filtered speed of the axis.
