시변지연과 미지 제어 방향과 비억제 성장율을 갖는 피드포워드 비선형 시스템의 안정화

Abstract

In this study, we investigate the regulation problem of a feedforward nonlinear system with time-varying state delay, an unknown control direction, and an unbounded growth function. The proposed controller was mainly developed using the Nussbaum gain and gain scaling techniques, and a rigorous system analysis was carried out to show that the controller achieved global regulation of the considered system. Numerical simulation results are provided to demonstrate the effectiveness of the proposed controller.
