Observer Based Fuzzy Terminal Sliding Mode Controller Design for a Class of Fractional Order Chaotic Nonlinear Systems

This paper presents a new observer based fuzzy terminal sliding mode controller design for a class of fractional order nonlinear systems. Robustness against uncertainty and disturbance, the stability of the close loop system and the convergence of both the tracking and observer errors to zero are the merits of the proposed the observer and the controller. The high gain observer is applied to es...

An Adaptive Grey Fuzzy PID Controller With Variable Prediction Horizon

The concept of grey system theory, which has a certain prediction capability, offers an alternative approach for various kinds of conventional control methods, such as PID control and fuzzy control. For instance, grey PID type fuzzy controller designed in this paper, can predict the future output values of the system accurately. However, the forecasting step-size of the grey controller determin...

A natural observer-based adaptive controller for structurally perturbed second order distributed parameter systems

In this note we consider a class of second order distributed parameter systems with structured perturbations ζ̈(t)+D ζ̇(t)+K ζ(t) = Bu+B f1(yp)+B f2(yv) and with partial position and velocity measurements: yp(t) = Cpζ(t), yv(t) = Cvζ̇(t). It is desired to design a controller so that the plant follows the reference model ζ̈m +Dmζ̇m(t)+Kmζm(t) = Br(t). The proposed model reference adaptive controller ...
