Description

VLO is a parameter of the Luenberger Velocity Observer. To reduce the delay of the derivation the observer can be served with the torque component of the current. The effective inertia is estimated by the gain of the velocity loop (GV). Setting VLO to zero the acceleration will not influence the observer. With a value of 1 the acceleration is full enabled. With VLO 0.5 the Observer will use 50% of the acceleration torque. Reducing VLO can result in an instable velocity loop.
