Abstract With the application to water industry of the Industry 4.0 approach (i.e. the Water 4.0 approach), Real Time Control is gaining attention as a strategic tool for the management of Water Distribution Networks. Moreover, this approach favours the installation of a wired communication infrastructure, which guarantees new standards in communication between sensors, actuators and control units. This work focuses on the particular task of service pressure regulation, obtained by means of a closed-loop control based on Pressure Control Valves and frequency domain control algorithms. While the topics of the identification of proper control structures, and the analysis of their stability and robustness properties were covered in previous works, this paper is aimed at improving the design phase of such algorithms by formulating the regulator tuning problem as a bi-objective optimisation one. Its solution leads to a Pareto front that captures the typical design trade-off between regulation performances and control effort and robustness, and helps the designer selecting the favoured tunings to be tested on the plant. Simulations performed on a detailed model of two different WDNs highlight the benefits of the approach and the reliability of the obtained tunings.

基于双目标优化的配水网络压力控制算法调整

摘要 随着工业 4.0 方法（即水 4.0 方法）在水行业的应用，实时控制作为配水管网管理的战略工具越来越受到关注。此外，这种方法有利于安装有线通信基础设施，这保证了传感器、执行器和控制单元之间通信的新标准。这项工作侧重于服务压力调节的特定任务，通过基于压力控制阀和频域控制算法的闭环控制获得。虽然之前的工作涵盖了识别适当控制结构以及对其稳定性和鲁棒性特性的分析等主题，本文旨在通过将调节器调谐问题制定为双目标优化问题来改进此类算法的设计阶段。它的解决方案导致了帕累托前沿，它捕获了调节性能与控制工作和稳健性之间的典型设计权衡，并帮助设计人员选择要在工厂进行测试的偏好调整。在两个不同 WDN 的详细模型上执行的模拟突出了该方法的优点和所获得调谐的可靠性。
