The paper deals with the steady-state response of a feedback control system to the canonical inputs. For its characterization it seems useful to introduce the notion of accuracy index mi beside the standard notion of loop type v. This index is assumed to be equal to the power of t in the analytic expression of the canonical input that leads to a finite nonzero deviation between the actual and the desired responses. When applied in the control design procedure, the accuracy index mi allows to achieve a steady-state performance that is more satisfactory than the one obtainable with reference to the loop type only. The conditions under which a single-loop feedback control system exhibits a prescribed value of mi, given the value of v, are derived and discussed with particular regard to their robustness.
