Preliminary Results about Anti-windup Strategy for Systems Subject to Actuator and Sensor Saturations
نویسنده
چکیده
This paper addresses the problems of the design of anti-windup schemes for linear systems subject to amplitude limitations in actuator and sensor. The design of anti-windup loops, using both measured and estimated variables, is considered in order to enlarge the region of stability of the closed-loop system, whereas some performance in terms of bounded controlled output is guaranteed. Based on the modelling of the closed-loop saturated system including the observer loop as a linear system with dead-zone nested nonlinearities, constructive stability conditions are formulated in terms of linear matrix inequalities by using Finsler’s Lemma.

Anti-windup compensation for systems with sensor saturation: a study of architecture and structure
This paper proposes a linear dynamic anti-windup strategy for the alleviation of performance and stability problems in systems which are linear apart from saturating sensors. Unlike anti-windup compensation for systems subject to actuator saturation, there is no agreed architecture for applying anti-windup to systems with sensor saturation and therefore attention is devoted to the discussion of...
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 کاملAn Anti-Windup Input-Output Linearization Scheme for SISO Systems
A control synthesis scheme for the feedback linearization of single-input single-output nonlinear systems subject to constraints is presented. The approach requires an external, statedependent saturation element, which translates the actuator bounds to the feedback linearizing control input. Thus the \linearizing" properties of the di erential geometric controller are preserved, and a linear an...

In this paper, we propose a design method of a static anti-windup compensator for systems with input magnitude and rate saturations. First, we present an anti-windup controller for systems with input magnitude and rate saturations. Then, we show that the design problem of the anti-windup compensator that guarantees the local stability of the closed-loop system against saturation nonlinearities ...
