TLDR
This paper investigates an adaptive fuzzy tracking control design problem for single-input and single-output uncertain nonstrict feedback nonlinear systems and proposes both adaptive fuzzy state feedback and observer-based output feedback control designs.Abstract:
This paper investigates an adaptive fuzzy tracking control design problem for single-input and single-output uncertain nonstrict feedback nonlinear systems. For the cases of the states measurable and the states immeasurable, fuzzy logic systems are separately adopted to approximate the unknown nonlinear functions or model the uncertain nonlinear systems. In the unified framework of adaptive backstepping control design, both adaptive fuzzy state feedback and observer-based output feedback control design schemes are proposed. The stability of the closed-loop systems is proved by using Lyapunov function theory. The simulation examples are provided to confirm the effectiveness of the proposed control methods.read more

Adaptive output-feedback control design with prescribed performance for switched nonlinear systems
TL;DR: An output feedback control method with prescribed performance is proposed for single-input and single-output (SISO) switched non-strict-feedback nonlinear systems and it is shown that all the signals in the resulting closed-loop system are semi-globally uniformly ultimately bounded.

Observer-Based Fuzzy Adaptive Event-Triggered Control for Pure-Feedback Nonlinear Systems With Prescribed Performance
TL;DR: This paper studies the problem of fuzzy adaptive event-triggered control for a class of pure-feedback nonlinear systems, which contain unknown smooth functions and unmeasured states, and relaxes the restrictive condition that the partial derivatives of system functions need to be known for pure- feedback non linear systems.

Observer-Based Adaptive Fuzzy Tracking Control for Strict-Feedback Nonlinear Systems With Unknown Control Gain Functions
TL;DR: A novel observer-based adaptive fuzzy output-feedback backstepping control method that can make the control system be semiglobally uniformly ultimately boundedness (SGUUB) and keep the observer and tracking errors to remain in a small neighborhood of the origin.

TL;DR: Two new robust adaptive control algorithms are developed by introducing a well defined smooth function and using a Nussbaum function to compensate for the nonlinear term arising from the input saturation.
