Optimal Design of Pole Placement Systems for a Minimum Phase Plant with Input Noise

摘要

In this paper, a design of optimal controller for discrete-time minimum phase systems with input noise is presented. It is shown that the optimal structure of closed-loop is an inversed interactoring system. In this systems, the choise of interactor and observer polynomials are given so as to be optimal for the input noise. Both full-order and reduced-order observer cases are considered. Numerical examples are also shown to confirm the validity of the proposed method.
