Abstract

This paper addresses the problem of model matching control for a class of systems modeled as input/output asynchronous sequential machines. Based on the feedback control scheme, we design a corrective controller that compensates the behavior of the closed-loop system so as to match a reference model. Whereas the former studies use state observers and the output burst for designing a controller, the present research needs neither the observer nor the output burst in controller design. We define the 'output equivalent machine' of the considered machine to describe the existence condition and the construction algorithm for the proposed controller. A case study is provided to show the operation of the proposed corrective controller.

본 논문은 입력/출력 비동기 순차 머신으로 모델링되는 시스템에 대한 모델 정합 제어 문제를 다룬다. 피드백 제어 기법을 이용하여 폐루프 시스템이 원하는 기준 모델의 상태 천이 특성을 가지도록 교정 제어기를 설계한다. 이전 연구에서는 제어기를 설계할 때 시스템의 상태를 관측하는 상태 관측기와 출력 피드백에 대한 burst 신호가 필요했으나 본 연구에서는 관측기와 출력 burst를 사용하지 않는 새로운 교정 제어기를 제안한다. 본 논문에서는 제어 대상 시스템의 '출력 등가 머신'을 정의하여 새로운 제어기의 존재 조건과 설계 과정을 기술한다. 또 사례 연구를 통해 모델 정합을 위한 교정 제어기의 동작 과정을 설명한다.
