Abstract :
In systems with signal-error feedforward, the recently suggested method of compensated signal takeoff can be used to extend the improvement of feedforward control to the output signal adder. A system using this quasifeedforward is compared with a feedback system consisting of similar components. The dynamic stability and the improvement obtained with both control methods are analysed.
