Abstract

This study explores a design method for electrical control systems based on the Digital Twin (DT) from the perspective of control engineers. The proposed method enables engineers to systematically develop and validate such systems, thereby enhancing the quality and efficacy of industrial digitalization. By identifying critical challenges in DT-based control system design, we proposed a maturity evaluation framework to ensure that the DT's fidelity aligns with the requirements of control system design application scenarios. Subsequently, a comparative analysis of virtual and physical commissioning was conducted, leading to the formulation of a structured implementation framework for DT-based control system design. A six-floor elevator DT was employed as the controlled object to demonstrate the proposed method. A virtual commissioning platform was constructed to validate the feasibility and reliability of the control system. This approach provides actionable insights for the corresponding physical entity to optimize construction schemes, commissioning workflows, and operation adjustments. The practical results demonstrate that the proposed DT-based design method of the electrical control system enables high-fidelity validation of production line design, reduces resource consumption during physical equipment commissioning, and significantly enhances development efficiency and quality while shortening construction and commissioning timelines.

基于数字孪生的PLC控制系统设计的通用方法。
本研究从控制工程师的角度探讨一种基于数字孪生(DT)的电气控制系统设计方法。所提出的方法使工程师能够系统地开发和验证这些系统,从而提高工业数字化的质量和效率。通过识别基于DT的控制系统设计中的关键挑战,我们提出了一个成熟度评估框架,以确保DT的保真度符合控制系统设计应用场景的要求。随后,对虚拟调试和物理调试进行了对比分析,从而制定了基于dt的控制系统设计的结构化实施框架。以六层电梯DT为被控对象,对所提方法进行了验证。为验证控制系统的可行性和可靠性,搭建了虚拟调试平台。该方法为相应的物理实体提供可操作的见解,以优化施工方案、调试工作流程和操作调整。实践结果表明,提出的基于dt的电气控制系统设计方法能够实现生产线设计的高保真验证,减少了物理设备调试过程中的资源消耗,在缩短施工和调试时间的同时,显著提高了开发效率和质量。
