On the Robust Controller for Dynamic Systems using Some Fuzzy Design Features

چکیده
Design of an adaptive controller for complex dynamic systems is a big challenge faced by the researchers. In this paper, we introduce a novel concept of dynamic pole motion (DPM) for the design of an error-based adaptive controller (EBAC). The purpose of this novel design approach is to make the system response reasonably fast with no overshoot, where the system may be timevarying and nonlinear with only partially known dynamics. The E-BAC is implanted in a system as a nonlinear controller with two dominant dynamic parameters, the dynamic position feedback and the dynamic velocity feedback. In the design of this feedback adaptive controller, parameters of the controller are designed as a fuzzy function of the system error. The position feedback , and the velocity feedback , are continuously varying as a function of the system error . For illustrating the strength of this new approach, in this paper we give an example of a flexible robot with nonlinear dynamics. Keywords—Dynamic pole motion (DPM), Error-based adaptive controller (E-BAC), Nonlinear timevarying system

Design of robust carrier tracking systems in high dynamic and high noise conditions, with emphasis on neuro-fuzzy controller
The robust carrier tracking is defined as the ability of a receiver to determine the phase and frequency of the input carrier signal in unusual conditions such as signal loss, input signal fading, high receiver dynamic, or other destructive effects of propagation. An implementation of tight tracking can be understood in terms of adopting a very narrow loop bandwidth that contradict with the req...
متن کاملRobust H_∞ Controller design based on Generalized Dynamic Observer for Uncertain Singular system with Disturbance
This paper presents a robust ∞_H controller design, based on a generalized dynamic observer for uncertain singular systems in the presence of disturbance. The controller guarantees that the closed loop system be admissible. The main advantage of this method is that the uncertainty can be found in the system, the input and the output matrices. Also the generalized dynamic observer is used to est...
