The concept of automatic control and intelligent control has emerged in all walks of industry, as has the construction. In order to improve the automation level and reduce the curing cost of poured mass concrete, a distributed control system was designed. A serpentine double-cycle structured water-cooling tube arrangement is used to increase cooling efficiency. Sprinklers are used to spray and moisturize the concrete surface. control units based on microcontrollers are independent of each other, collecting data to control the process of water cooling and moisturizing, and communicate with industrial computer via LoRa IoT (Long Range Radio Internet of Things). control units collect sensor data via ITU bus and RS485 bus. The start and stop of water pipe cooling and spray moisturizing are controlled by control units through butterfly valves. The system adopts efficient hardware and software structure, uses different communication strategy. In application experiments, the control system can effectively improve the efficiency of water pipe cooling and spray moisturization.

The distributed system and multi-agent system (MAS) enable the effective and efficient management of complex distribution network. How to realise the co-simulation with a large number of controllers for these systems is being a hot issue. In this study, the characteristics of the simulation environment, which is suitable for the distributed control system, are discussed, and a new co-simulation method based on Java agent development framework (JADE) is proposed. It fits for the simulation of distributed system and MAS, and can simulate the physical and the communication models concurrently. After the introduction of co-simulation environment, the modelling methods of distributed controllers are described in detail. Finally, a comprehensive evaluation on the distributed protection algorithm is carried out by means of the co-simulation, and the effectiveness of the proposed co-simulation environment is validated.

In this paper, by using a distributed control system (DCS) device, a robust tracking control system is proposed based on robust right coprime factorization for a heat exchanger actuated by a water level process with coupling effects and uncertainties. Firstly, nonlinear models of water level and temperature processes with coupling and uncertainties are given. Secondly, nonlinear feedback tracking control systems corresponding to a multi-input multi-output (MIMO) process are realized by using operator-based robust right coprime factorization. Meanwhile, stability of the control systems is guaranteed by using robust stability conditions compatible with the MIMO process including coupling effects, and to improve the output tracking performance, tracking controllers are designed. Finally, the effectiveness of the proposed design scheme is confirmed by simulation and experimental results.

The robotics field provides with many typical applications of Cyber-Physical systems (CPS). Robots are expected to be deployed in a wide variety of applications including life supporting work or disaster response and therefore they need to follow strict safety and dependability constraints. In order to create robots with high utility, safety and dependability, research has focused both on creating mechanically safe systems and safe control laws. Throughout the present work, we use the embedded real-time processor D-RMTP as a motor controller to attain high responsiveness on a high power robot. D-RMTP has a hardware mechanism to support hard real-time processing, which enables lower-jitter and lower-overhead processing compared with conventional software based real-time execution (Real-Time Task). Responsive Task, a real-time execution mechanism based on D-RMTP, has also been proposed in recent works. In this paper, we have evaluated the effects of the low-jitter and low-overhead performance of Responsive Task on a distributed robot control system. The result of the experiment showed that Responsive Task resulted in improving the control cycle speed and the responsiveness of the controller.

In fiber spectroscopic telescopes, we propose a method of wire communication to control the fiber positioning nodes which are driven by two stepping motors. Taking the integration CAN control chip as main controller, the hardware of CAN intelligent node and adapter is designed to be the bottom hardware platform for the multi-motor distributed control system. The results proved that the system has good real-time performance and stability, and is able to realize not only CAN bus communication but also PC supervisory control, fundamentally meet the requirements of real-time precise position measurement of the optical fibers.

A secure and highly reliable communication network is a crucial component of the distributed control system (DCS) in nuclear power plants (NPPs), particularly for the protection system. However, there have been numerous reported cases of cyber-attacks in the field of nuclear power, and the cybersecurity threats faced by a DCS are increasing. Given that the DCS is a complex integrated system combining computers, communication, and control with a large number of interactions between components and external interferences, traditional linear safety analysis methods fail to meet its requirements. To minimize cybersecurity accidents caused by potential vulnerabilities, it is necessary to conduct systematic safety analysis on DCS cybersecurity accidents in NPPs. Therefore, this paper selected a specific case of cybersecurity accidents in a NPP for abstract modeling and reproduction. The causal analysis based on system theory (CAST) method was applied to conduct an analysis of the accident causes. It can identify existing vulnerabilities and potential factors impacting the safe operation of NPPs, and countermeasures and recommendations can be proposed. The reference for assessing potential risks and devising solutions can be provided for other DCS communication networks.

Fault tolerance or resiliency aspects of large-scale systems with networked embedded sensors and actuators need to be taken into consideration at design time and not be an after-the-fact addition to an already completed (not necessarily faulttolerant) design. While there has been some important progress in fault-tolerant distributed control systems, most of the recent work has focused on specific systems and provide answers in particular domains, but offer little insight for other applications. The paper presents such fault-tolerant distributed control system architecture, using robust fractional order controllers. The controller design algorithm is based on a bio-inspired optimization method. The simulation results highlight the advantages of the control system in different fault scenarios.
