Operational Technology (OT) systems are merging towards a conjoint architecture with the advances in communication networks and emerging standards such as IEC/IEEE 60802 for industrial automation, automotive, power and energy and other areas. In this paper, we present a Dependable Control System (DepCS) with Model Predictive Control (MPC) algorithm that works in such architectures using multiple MPC controllers (of a feedback control loop) to enhance the operational reliability. We termed this as Dependable Model Predictive Control (DepMPC) system. The reliability enhancement of a DepMPC system is achievable thanks to the fault-tolerance of multiple MPC controllers and the tractable information flows with Time-Sensitive Networking (TSN). Here, our discussion was focused only on the logical connectivity and not the hardware architecture. The numerical simulations are studied with three multi-variable plants that have control constraints. In this study, we introduced a Replacement Controller (RC) to improve the control performance of the DepMPC system. The combination of both the Replacement Controller and Dependable Model Predictive Control (RC-DepMPC) system proves a promising solution for actual implementations.
随着通信网络的发展以及诸如用于工业自动化、汽车、电力和能源等领域的IEC/IEEE 60802等新兴标准的出现，运营技术（OT）系统正朝着联合架构发展。在本文中，我们提出了一种具有模型预测控制（MPC）算法的可靠控制系统（DepCS），该系统在这种架构中运行，使用多个（反馈控制回路的）MPC控制器来提高运行可靠性。我们将其称为可靠模型预测控制（DepMPC）系统。由于多个MPC控制器的容错能力以及时间敏感网络（TSN）中易于处理的信息流，DepMPC系统的可靠性得以提高。在此，我们的讨论仅集中在逻辑连接性上，而非硬件架构。使用三个具有控制约束的多变量工厂进行了数值模拟。在本研究中，我们引入了替换控制器（RC）以提高DepMPC系统的控制性能。替换控制器和可靠模型预测控制（RC-DepMPC）系统的结合为实际应用提供了一个很有前景的解决方案。
