Sliding Mode Controller Design Based On The Fuzzy Observer For Uncertain Nonlinear System

불확실한 비선형 시스템의 퍼지 관측기 기반의 슬라이딩 모드 제어기 설계

In adaptive fuzzy control systems. fuzzy systems are used to approximate the unknown plant nonlinearities. Until now. most of the papers in the field of controller design for nonlinear system using fuzzy systems considers the affine system with fixed grid-rule structure based on system state availability. This paper considers observer-based nonlinear controller and dynamic fuzzy rule structure. Adaptive laws for fuzzy parameters for state observer and fuzzy rule structure are established so that the whole system is stable in the sense of Lyapunov.
