“…A model-based approach encompasses both physical and numerical models. Zhang et al [2] analyzed the common failure modes and causes of key valves based on physical models and proposed a real-time intelligent maintenance scheme for natural gas pipeline valves. Solís et al [3] divided the mathematical model-based BLDC motor stator fault diagnosis methods into two categories, including those without estimated error feedback and those with estimated error feedback.…”

The control system of unmanned vehicles must demonstrate strong capability to promptly diagnose and address system faults. Such a capability can improve transportation efficiency, ensure the smooth execution of production tasks, and to a certain extent, mitigate the risk of human casualties. To ensure the upkeep of unmanned vehicles and address the diagnostic requirements of control systems, this study integrates traditional wheeled vehicle control systems with digital twin (DT) technology to establish a framework for control system fault diagnosis and maintenance, with the primary objective of fulfilling the fault diagnosis task. By this framework, a method for detecting faults in unmanned vehicle control systems based on DT technology has been developed. This method involves the design of a data-driven model using multiple sensors and the application of a DT-improved particle filter fault diagnosis algorithm, utilizing a multi-domain model approach. A case study of the proposed method and simulation results are presented to illustrate its feasibility.

“…Working environments can be under high pressure up to hundreds of atmospheres and at temperatures from close to absolute zero to thousands of degrees [5,6]. Fittings include a number of mechanisms mounted in collectors that regulate certain work flows [7]. Depending on the functional purpose, fittings are divided into different types: check valves, control, shut-off, safety, diverter, shutdown valves, etc.…”

This research aims to increase the reliability and safety of pipeline systems by creating an improved model range of Butterfly Check Valves (BCV). Pipes through which working fluids are transported, parts related to shut-off and control valves, control measuring instruments, fasteners, anticorrosion elements, and other structural components are the main elements that make up pipelines. Fittings can be of different types; BCV refers to protective ones. These devices protect pipelines by disconnecting the working line in the event of a sudden change in the transported fluid parameters (pressure, flow direction), resulting in the failure of the entire system. Based on an analysis of the key requirements for valves, namely reliability, tightness of a closed system, ensuring safe operation, and analysis of existing BCVs, the design of the presented valve was created. Improved overall dimensions and tightness, both in the open and closed states, as opposed to the existing analogs, are distinctive features of the developed design of butterfly check valves. To confirm the results, the authors, using the finite element method, calculated the stress–strain state of the structure under normal conditions and with regard to the maximum temperatures of the working fluid. The reliability indicators of the developed elements were also calculated to confirm their operability. As a result, it was concluded that after the developed valves have passed acceptance tests, the research findings will make it possible to increase the reliability and safety of the valve itself and the entire pipeline system by introducing these structures into enterprises.
