چکیده
Zusammenfassung Dieser Beitrag stellt eine neue, nichtlineare Anti-Windup-Maßnahme für lineare Systeme vor, die auf der weich strukturvariablen Zustandsregelung mittels impliziter Ljapunov-Funktionen basiert. Durch die variable Struktur des Anti-Windup (AW) kann zum einen die Regelgüte im Vergleich zu linearen AW-Ansätzen beträchtlich gesteigert werden. Der Vorteil gegenüber existierenden strukturvariablen AW-Strategien ist zum anderen ein geringerer Entwurfsaufwand und eine einfacher zu implementierende Regelstrategie bei gleicher Regelgüte, wie anhand eines Beispiel demonstriert wird. Summary This article presents a new, nonlinear anti-windup for linear systems. It is based on soft variablestructure controls using implicit Lyapunov functions leading to remarkable performance improvements compared to linear AW techniques. Advantages compared to existing variable-structure AW approaches are a less complicated design and an easily implementable control strategy. The effectiveness is demonstrated by an example.

Entwurf von modellbasierten Anti-Windup-Methoden für Systeme mit Stellbegrenzungen
Neglecting actuator limitations when designing a feedback control may cause a severe malfunctioning of the control loop during operation. This faulty behavior is often termed windup and manifests itself in intense oscillations, a significantly prolonged settling time or even instability. The main objective of this work is the development of systematic design methods for anti-windup strategies, ...
متن کاملRobust Anti-Windup Control Design for PID Controllers–Theory and Experimental Verification
This paper addresses an approximation-based anti-windup (AW) control strategy for suppressing the windup effect caused by actuator saturation nonlinearity in proportional–integral–derivative (PID) controlled systems. The effect of actuator constraint is firstly regarded as a disturbance imported to the PID controller. The external disturbance can then be modeled by a linear differential equatio...

متن کاملModified Dynamic Anti-windup through Deferral of Activation
We consider the dynamic Anti-Windup design problem for linear systems with saturating actuators. The basic idea, proposed here, is to apply Anti-Windup only when the performance of saturated system faces substantial degradation. We provide synthesis LMIs to obtain the gains of the dynamic Anti-Windup compensator in a structure that delays the activation of the Anti-Windup. Benefits of the propo...
متن کاملL2 anti-windup for linear dead-time systems
In this paper we address and solve the problem of anti-windup augmentation for linear systems with input and output delay. In particular, we give a formal definition of an optimal L2 gain based antiwindup design problem in the global, local, robust and nominal cases. For each of these cases we show that a specific anti-windup compensation structure (which is a generalization of the approach in ...
