Practical issues in multirate output controllers

Abstract

Multirate output controllers are a new type of controller which detect the ith output of the plant Ni times and change the plant input once during a period To. Important features of this type of controller includeequivalent realization of state feedback and strong stabilization. Above all, they distinguish themselves from multirate input controllers in that they appear more suitable for industrial application. Nevertheless, there are some potential problems that can degrade the operation of the controller. In this paper, these problems are highlighted and approaches to avoid them are provided. Show more
