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.

运营技术（OT）系统正在随着通信网络的发展和新兴标准（例如用于工业自动化，汽车，电力和能源及其他领域的IEC / IEEE 60802等）的融合而走向联合架构。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），该算法在这样的体系结构中使用多个MPC控制器（反馈控制回路）来提高操作可靠性。我们称其为可靠模型预测控制（DepMPC）系统。得益于多个MPC控制器的容错能力以及具有时间敏感网络（TSN）的易处理信息流，DepMPC系统的可靠性得以提高。在这里，我们的讨论仅集中在逻辑连接上，而不是硬件体系结构上。使用具有控制约束的三个多变量工厂研究了数值模拟。在这项研究中，我们引入了替代控制器（RC）来改善DepMPC系统的控制性能。替换控制器和可靠模型预测控制（RC-DepMPC）系统的结合为实际实现提供了有希望的解决方案。
