- Abstract
- 본 논문에서는 미지의 외란을 갖는 비선형 출력 피드백 시스템에 대한 강인적응 제어를 제안하였다.
In this paper, we address the robust adaptive backstepping controller using fuzzy neural network (FNN) for a class of uncertain output feedback nonlinear systems with disturbance. A new algorithm is proposed for estimation of unknown bounds and adaptive control of the uncertain nonlinear systems. The state estimation is solved using Kᅳfilters. Ail unknown nonlinear functions are approximated by FNN. The FNN weight adaptation rule is derived from Lyapunov stability analysis and guarantees that the adapted weight error and tracking error are bounded. The compensated controller is designed to compensate the FNN approximation error and external disturbance. Finally, simulation results show that the proposed controller can achieve favorable tracking performance and robustness with regard to unknown function and external disturbance.
