Abstract
The most advanced technology in Industry 4.0 is the digital twin, which utilizes a fusion of virtual and physical elements, precise mapping, and multi-dimensional vision to depict the virtual-physical environment in real-time. It is vital for simulation, control, optimization, and prediction and is growing in popularity, especially in industrial automation. Fluid Power Application is a crucial industrial automation system because it provides precise control, enormous power, adaptability, dependability, affordability, and ease of integration into existing automated systems using hydraulic and pneumatic system’s power. However, emerging digital twin technology, robust framework, and applications in fluid power systems emphasize distinct technological aspects at various stages, a phenomenon that has not yet been thoroughly examined. Thus, this article aims to provide a thorough review of digital twin technology in fluid power applications considering their significance in the industrial sector, followed by an in-depth examination of each component necessary for developing digital twin of fluid power applications. This review paper contributes to academic knowledge by emphasizing the fundamental concepts and constituents of digital twin, particularly within the context of fluid power applications, and serving as a driving resource for digital twin in fluid power applications’ ongoing research attempts and advancements.
