Abstract

A general discretization method for input-driven nonlinear continuous time-delay systems is proposed, which can be applied to general order sampling hold assumptions. It is based on a combination of Taylor series expansion and the theories of sampling and hold. The mathematical structure of the new discretization scheme is introduced in detail. The performance of the proposed discretization procedure is evaluated by two degrees of systems. The results show that the proposed scheme is applicable to control systems.

본 논문에서는 입력에 시간지연이 있는 연속 비선형 시스템의 일반적인 이산화를 위해 높은 차수의 샘플링 보관법을 제안한다. 제안한 방법은 테일러 시리즈 확장, 샘플링 이론과 보관법의 조합을 기초로 한다. 새로운 이산화 방법의 수학적인 구조에 대해 세부적으로 유도하였으며, 제안한 이산화 방법에 대한 성능을 2차 시스템에 대한 시뮬레이션을 통해 검증하였다.
