چکیده

Zusammenfassung Der Beitrag beschreibt ein LyapunovFunktionen-basiertes Führungsfilter für lineare Strecken mit Stellgrößenbegrenzung. Ziel des Filters ist es, die Abhängigkeit zwischen der zu stabilisierenden Ruhelage und der Größe des mit Lyapunov-Funktionen nachweisbaren Einzugsbereichs zu überwinden. Hierdurch kann erreicht werden, dass für alle Ruhelagen im System der gleiche Einzugsbereich nachgewiesen werden kann. Dieser umfasst die Vereinigungsmenge aller Abschätzungen ohne Führungsfilter. Summary This paper presents a Lyapunov function based method for generating set points for linear systems with input saturation. Aim of the method is to overcome the dependecy between the place of the equilibrium point and the size of its approximated domain of attraction shown by Lyapunov functions. As a result all equlibrium points of a system share the same approximation for their domain of attraction, which is formed by the set union of all former approximations without the set point generator.

Estimation of the Domain of Attraction of Free Tumor Equilibrium Point for Perturbed Tumor Immunotherapy Model

In this paper, we are going to estimate the domain of attraction of tumor-free equilibrium points in a perturbed cancer tumor model describing the tumor-immune system competition dynamics. The proposed method is based on an optimization problem solution for a chosen Lyapunov function that can be casted in terms of Linear Matrix Inequalities constraint and Taylor expansion of nonlinear terms. We...

Lyapunov-Based Robust Power Controllers for a Doubly Fed Induction Generator

In this work, a robust nonlinear control technique of a doubly fed induction generator (DFIG) intended for wind energy systems has been proposed. The principal idea in this article is to decouple the active and reactive power of the DFIG with high robustness using the backstepping strategy. The principle of this control method is based on the Lyapunov function, in order to guarantee the global ...

Studying Transition Behavior of Neutron Point Kinetics Equations Using the Lyapunov Exponent Method

The neutron density is one of the most important dynamical parameters in a reactor. It is directly related to the control and stability of the reactor power. Any change in applied reactivity and some of dynamical parameters in the reactor causes a change in the neutron density. Lyapunov exponent method is a powerful tool for investigating the range of stability and the transient behavior of the...

Discussion on: ''Exponential Stability Based Design of Constrained Fuzzy Predictive Control''

Predictive control of nonlinear systems subject to output and input constraints is considered. A fuzzy model is used to predict the future behavior. Three new ideas are proposed here. First, an added constraint on the applied control action is used to ensure the decrease of a quadratic Lyapunov function, and so guarantee Lyapunov exponential stability of the closed-loop system. Second, the feas...

Lyapunov Function Analysis of Power Systems with Dynamic Loads

A recently developed Lyapunov (energy) function incorporates both generator and load dynamics. This paper reviews that energy function. Its use in the assessment of the stability of power systems where generator and load dynamics are active is presented. Further, generator/load interaction is explored. This new energy function allows for direct assessment of (dynamic) voltage collapse scenarios...
