4.4.1.1 Stiffness of the speed controller
The stiffness is proportional to the control loop speed.
Nominal value: 100%
On increasing stiffness:
Control action becomes faster. The control loop oscillates above a critical threshold
value. Set the stiffness with an adequate safety margin with respect to the
oscillation threshold value.
On decreasing stiffness:
Control action becomes slower. This increases the tracking error. Current limiting
will be reached later.
