This article aims to design proportional-derivative (PD) controllers for interval positive linear systems in the continuous-time domain, ensuring both closed-loop system stability and positivity. The work proposes a systematic framework and presents methodology and algorithm, which are validated by numerical examples.
This article aims to design proportional-derivative (PD) controllers for interval positive linear systems in the continuous-time domain, which still remains a widely-discussed open problem in positive systems theory. The specific objective is to design a PD controller for the system with interval uncertain parameters and time-varying delay, which simultaneously ensures closed-loop system stability and preserves positivity. The work proposes a systematic framework, with the aim of finding PD controller gains for positive robust stabilization. The methodology and algorithm are presented first in the study, and the performance of such methods is instantiated by numerical examples. (c) 2021 Elsevier Inc. All rights reserved.
