About incremental stability interest when analysing anti-windup control law performance

چکیده
A classical approach to deal with is the anti windup design [11, 13]. A controller is first designed ignoring the input saturations. It is then modified to take into account the effects of the saturation nonlinearities [3]. The last step is the verification of the stability and the performance of the closed loop system. This approach was considered in a significant number of works [11, 13] and actually is widely applied in practise. Nevertheless, the main issue is to ensure that the anti-windup control actually ensures the expected performance level.

Robust 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...

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, ...

n this article we give a simple and comprehensive review of I anti-windup, bumpless and conditioned transfer techniques in the framework of the PID controller. We will show that the most suitable anti-windup strategy for usual applications is the conditioning technique, using the notion of the realizable reference. The exception is the case in which the input limitations are too restrictive. In...
متن کاملNovel Anti-windup PID Controller Design under Holonomic Endpoint Constraints for Euler-Lagrange Systems with Actuator Saturation
A novel anti-windup PID controller design method under holonomic constraints is proposed for nonlinear Euler-Lagrange systems with actuator saturation. The controller design is based on passivity, quasi-natural potential and saturated-position feedback. According to four saturation cases, switching of four integrating functions in the control law is utilized and four Lyapunov functions, such as...
