Design of CNF-Based Nonlinear Integral Sliding Surface for Matched Uncertain Linear Systems with Multiple State-Delays
طراحی سطح لغزش انتگرالی غیرخطی بر پایه CNF برای سامانه های خطی نامعین تطبیق یافته دارای تأخیرهای زمانی چندگانه
Abstract


This paper presents an approach of achieving high performance and robustness for matched uncertain multi-input multi-output linear systems with external disturbances and multiple state-delays, which are often encountered in practice and are frequently the sources of instability. This scheme is based on composite nonlinear feedback and integral sliding mode control methods. The selection of nonlinear function and the existence of sliding mode are two important issues, which have been addressed. The control law is designed to guarantee the existence of the sliding mode around the nonlinear surface, and the damping ratio of the closed-loop system is increased as the output approaches the set-point. Simulation results are presented to show the effectiveness of the proposed method as a promising way for controlling similar nonlinear systems.
