Anti-windup Design for Mitigation of Input Saturation in a Time-Delayed Interval Positive System
摘要
This article addresses the mitigation of the adverse effect of input saturation in a continuous time-delayed positive linear system (PLS) with interval uncertainties. Considering that an observer-based static feedback controller has already been developed to stabilize the time-delayed interval PLS (without saturation), a novel method is proposed to determine an anti-windup (AW) gain to mitigate the adverse effects of input saturation. The proposed method illustrates how the entire closed-loop (CL) system (controller incorporated with AW gain) can be represented through a PLS framework that integrates a dead-zone nonlinearity. The stability analysis is done using the Lyapunov function, ensuring that within the domain
