In this paper, the Steering Along Zeros Control technique for achieving a stable inversion of discrete-time non-minimum- phase linear systems is presented. It is shown how the problem reduces to the computation of an ideal initial state from which perfect tracking of a given reference signal can be achieved with a bounded control effort. A case study is presented relative to the control of a one-link flexible arm.
