Abstract
The paper deals with some specific feedback solutions to tracking problems for discrete linear SISO systems, characterized by a finite length control sequences (FLC) and by an infinite or a finite length error sequences. A complete set of all 2DoF FLC controllers for plants exposed to general disturbances (2DoF GFLC) is determined and it is shown that this set embeds the set of deadbeat ripple-free controllers (2DoF GDBRF), which moreover produce a finite length error sequences.
