Abstract

In System of Systems Engineering (SoSE), robustness and reliability are essential for operations under various conditions. Distributed control approaches demonstrate superior performance for handling changes in highly scalable systems, making them suitable for this context. The study explores the efficacy of the Alternating Direction Method of Multipliers (ADMM) applied in a simulated case study and on a physical Quadruple Tank Plant system. In this work, a multi-agent coordination problem using the Model Predictive Control (MPC) paradigm, Linear Quadratic Tracking (LQT) techniques, and ADMM for the consensus has been formalized and a solution has been proposed as a control algorithm. During the experiments, there was no assumption of feasibility when the references were chosen. To improve the reliability of the controller, a Kalman filter to estimate the state has been added.

系统系统分布式控制中的乘法器交替方向法：应用于四联罐工厂

在系统工程（SoSE）中，稳健性和可靠性对各种条件下的运行至关重要。分布式控制方法在处理高度可扩展系统中的变化方面表现出卓越的性能，因此适用于这种情况。本研究探讨了交替方向乘法（ADMM）在模拟案例研究和物理四联罐工厂系统中的应用效果。在这项工作中，使用模型预测控制（MPC）范例、线性二次跟踪（LQT）技术和 ADMM 达成共识的多代理协调问题被正式化，并作为控制算法提出了解决方案。在实验过程中，在选择参照物时没有假设可行性。为了提高控制器的可靠性，增加了卡尔曼滤波器来估计状态。

期刊介绍： Control Engineering Practice strives to meet the needs of industrial practitioners and industrially related academics and researchers. It publishes papers which illustrate the direct application of control theory and its supporting tools in all possible areas of automation. As a result, the journal only contains papers which can be considered to have made significant contributions to the application of advanced control techniques. It is normally expected that practical results should be included, but where simulation only studies are available, it is necessary to demonstrate that the simulation model is representative of a genuine application. Strictly theoretical papers will find a more appropriate home in Control Engineering Practice''s sister publication, Automatica. It is also expected that papers are innovative with respect to the state of the art and are sufficiently detailed for a reader to be able to duplicate the main results of the paper (supplementary material, including datasets, tables, code and any relevant interactive material can be made available and downloaded from the website). The benefits of the presented methods must be made very clear and the new techniques must be compared and contrasted with results obtained using existing methods. Moreover, a thorough analysis of failures that may happen in the design process and implementation can also be part of the paper. The scope of Control Engineering Practice matches the activities of IFAC. Papers demonstrating the contribution of automation and control in improving the performance, quality, productivity, sustainability, resource and energy efficiency, and the manageability of systems and processes for the benefit of mankind and are relevant to industrial practitioners are most welcome.
