Stable and robust fuzzy control for uncertain nonlinear systems
This paper presents the stability and robustness analysis for multivariable fuzzy control systems subject to parameter uncertainties based on a single-grid-point (SGP) approach. To perform the analysis, we represent a multivariable nonlinear system using a TS-fuzzy plant model. Three design approaches of fuzzy controllers are introduced to close the feedback loop. By estimating the matrix measu...
متن کاملStable and Robust Fuzzy Control for Uncertain Nonlinear Systems Based on a Grid-Point Approach'
This paper presents the stability and robustness analyses of uncertain nonlinear control systems. TO proceed with the analysis, the uncertain nonlinear system is represented by a fuzzy model with uncertainties. Based on this model, under a single-grid-point (SGP) approach, a fuzzy controller is designed to close the feedback loop. A simple stability criterion is derived by estimating the norm o...
متن کاملRobust adaptive control for nonlinear uncertain systems
A direct robust adaptive control framework for non linear uncertain systems with constant linearly parame terized uncertainty and nonlinear state dependent uncer tainty is developed The proposed framework is Lyap unov based and guarantees partial asymptotic robust sta bility of the closed loop system that is asymptotic robust stability with respect to part of the closed loop system states assoc...
متن کاملStable Adaptive Fuzzy PID Controller for Nonlinear Uncertain Systems
Abstract This paper investigates an improved fuzzy adaptive control scheme for a class of nonlinear uncertain systems. A fuzzy system, whose inputs are the feedback error signals instead of the state variables, is used to cancel the nonlinear function. By using the feedback errors as the inputs of the fuzzy system, the disturbance rejection performance can be achieved because the controller wil...
متن کاملRobust Adaptive Control of Uncertain Nonlinear Systems
An adaptive control problem for a class of uncertain nonlinear systems is formulated as a disturbance attenuation problem. In particular, the class of problems having nominal linear dynamics perturbed by small polynomial functions of the state which multiply the state, control and measurements is considered. Using a perturbation approach, an approximate solution to the resulting differential ga...
