Design of polynomial fuzzy observer-controller with membership functions using unmeasurable premise variables for nonlinear systems
In this paper, the stability of polynomial fuzzy-model-based (PFMB) observercontrol system is investigated via Lyapunov stability theory. The polynomial fuzzy observer with unmeasurable premise variables is designed to estimate the system states. Then the estimated system states are used for the state-feedback control of nonlinear systems. Although the consideration of the polynomial fuzzy mode...
متن کاملDesign of Polynomial Fuzzy Observer-Controller with Sampled-Output Measurements for Nonlinear Systems Considering Unmeasurable Premise Variables
In this paper, we propose a polynomial fuzzy observer-controller for nonlinear systems where the design is achieved through the stability analysis of polynomial-fuzzymodel-based (PFMB) observer-control system. The polynomial fuzzy observer estimates the system states using estimated premise variables. The estimated states are then employed by the polynomial fuzzy controller for the feedback con...
متن کاملMulti-objective H =H1 fault detection observer design for Takagi–Sugeno fuzzy systems with unmeasurable premise variables: descriptor approach
This paper investigates the problem of robust fault detection observer design for nonlinear Takagi–Sugeno models with unmeasurable premise variables subject to sensor faults and unknown bounded disturbance. The main idea is to synthesize a robust fault detection observer by means of a mixed H =H1 performance index. The considered observer is used to estimate jointly states and faults. Using the...
متن کاملReduced-order observer design for descriptor systems with unknown inputs
A new method for the design of reduced-order observers for descriptor systems with unknown inputs is presented. The approach is based on the generalized constrained Sylvester equation. Sufficient conditions for the existence of the observer are given.
متن کاملObserver design and fault tolerant control of Takagi-Sugeno nonlinear systems with unmeasurable premise variables∗
Dealing with real systems (electrical, mechanical, economic, chemical, . . . ) one is often urged to use nonlinear representations in order to accurately capture the whole behavior of the systems under study. The linear modeling of such systems only has a local validity, but it considerably eases the performance analysis and the controller supervision module designs. Even if a considerable amou...
