Finite Settling-Time Controllers from the Process Transfer Matrix

In control literature a variety of deadbeat control algorithms is presented. In this paper a realization will be presented that is very well suited for process control. For a number of situations (unstable processes, nonminimum phase behaviour) elegant algorithms will be derived. The computation of the algorithms from the process transfer matrix is straightforward. The use of the algorithms will be demonstrated on the control of feed flow disturbances in a distillation column.
