Forward control measures
Forward control of rotation speed, acceleration and current
! Minimizes tracking error
! Improves the transient response
! Gives greater dynamic range with lower maximum current
A positioning is calculated in the target value plate and specified as the target value
for the position controller. This provides the target value plate with the preliminary
information on changes in speed, acceleration and current required for positioning.
Switching this information to the controller then makes it possible to reduce
tracking errors to a minimum. The transient response of the controller is also
improved and the drive dynamics are increased.
The stability of the control loop is unaffected by the forward control.
