Design of Nonlinear Observers Using Popov’s Criterion
نویسنده
چکیده
Recently there has been an intense activity in designing observers by means of the circle criterion. However, it is known that the use of Popov’s criterion reduces the conservativeness of stability analysis based on the circle criterion, if further restrictions are satisfied by the nonlinearity. It is shown in this paper that Popov’s criterion can indeed be used with advantage for observer design, reducing the restrictions of previous designs. Although only the scalar case will be considered here, it is possible to extend the results to a multivariable setting. Copyright c ©2005 IFAC

Absolutely Stable of Takagi-Sugeno Fuzzy Control System by Using Popov’s Criterion
In this paper, we presented a sufficient condition on the frequency domain for the absolutely stable analysis of the Takagi-Sugeno (T-S)fuzzy control system, based on the Popov’s criterion. we use some numerical examples to illustrate the efficiency of frequency domain-based condition.
متن کاملDesign of Direct Exponential Observers for Fault Detection of Nonlinear MEMS Tunable Capacitor
In this paper a novel method is proposed for construction of an exponential observer for nonlinear system. The presented method is based on direct solution of dynamic error without any linearzing of nonlinear terms. Necessary and sufficient conditions for construction of direct observer are presented. Stability of the observer is checked using Lyapunov theorem. Also the ability of this observer...
متن کاملFuzzy Observers for Takagi-Sugeno Models with Local Nonlinear Terms
The paper deals with the problem of nonlinear fuzzy observers for a class of continuous-time nonlinear systems, represented by Takagi-Sugeno models with local nonlinear terms. On the basis of the Lyapunov stability criterion and incremental quadratic inequalities, the sufficient LMI design conditions are outlined. Numerical example is given to illustrate the procedure and to validate the perfor...

This paper deals with the issues of sensor fault detection for a class of Lipschitz uncertain nonlinear system. By definition coordinate transformation matrix for system states and output system, at first the original system divided into two subsystems. the first subsystem includes uncertainties but without any sensor faults and the second subsystem has sensor faults but is free of uncertaintie...

Using Tracking Differentiators in Designing Nonlinear Disturbance Observers for Uncertain SystemsNaser Kazemzadeh, Saeed BarghandanAbstractIn the present paper, a practical designing method has been proposed for a novel class of NDOs based on TD. Such NDOs can nearly estimate all uncertain disturbances (specifically disturbances without prediction information). Regarding the outstanding perform...
