Disturbance Rejection Using SPR0 Substitutions

Abstract

The disturbance rejection, defined as the problem of designing control laws that ensure, where possible, exogenous disturbances  that do not affect the output of the perturbed system, has been resolved by means of algebraic and geometric techniques. This is a steady linear case by means of the static feedback state. Modifications of the Smith form through the SPR0 substitutions are presented which guarantees infinite zeros of a linear single input, single output (SISO) system.
