It is necessary to adapt the current or the ramp if there are vibrations during steady state.
7.6.3.6 Motor model
The motor model calculates an estimated speed from the motor data and the actual values of voltage and cur-
rent. Then this speed is admitted to the speed controller. The calculated model currents can be used also for
current control.
