Abstract
The ripples between the sampling points that can appear with the cancellation controllers can be avoided if a finite settling time is required for both the controlled variable and the manipulated variable. Jury [2.3, 7.1] has called this behaviour “deadbeat-response”. For a step change of the reference variable the input and the output signal of the process have to be in a new steady state after a definite finite settling time.
