Understanding Physical Digital Twins


Digital twins are virtual representations of physical entities or processes that are used to better understand and optimize their real-world counterparts. The concept of physical digital twins is relatively new, but it has already become a critical component in many industries, including manufacturing, logistics, and construction. In this article, we will discuss the concept of digital twins, the differences between physical digital twins and virtual digital twins, and the importance of physical digital twins in various industries.

Concept of Digital Twins

Digital twins are digital replicas of physical entities or processes that are created by collecting real-time data from various sources, such as sensors, actuators, and other connected devices. The data is then used to create a dynamic virtual model, which accurately mimics the behavior of the original physical entity or process under various conditions.

The main purpose of digital twins is to enable better decision-making and optimize various aspects of the physical entity, such as operational efficiency, resource utilization, and energy consumption. Digital twins can also be used to identify potential issues, test new designs, and predict the outcome of various scenarios without affecting the real-world counterpart.

Digital twins can be classified into two main types: physical digital twins and virtual digital twins, based on the nature of the physical entity or process they represent.

Physical Digital Twins vs. Virtual Digital Twins

Physical digital twins are digital replicas of tangible objects, such as machines, equipment, vehicles, and buildings.

There are several critical components of a Physical Digital Twin, such as real-time data collection, simulation models, machine learning/AI integration, visualization, and interaction tools. Understanding these components will allow one to utilize the full potential of this technology.

Real-Time Data Collection

A fundamental component of creating a digital twin is the ability to capture data from the physical environment in real-time. Real-time data collection is the process of collecting, monitoring, and analyzing data from physical systems as they are generated. This can include process variables, sensor data, control signals, and any other relevant information that describes the current state of the physical system. Real-time data is essential because it allows a digital twin to react and adjust to the changes in the physical world, enabling the model to stay up-to-date and accurate.

Modern digital twin systems collect data from a wide range of sources, including IoT devices, cameras, wearables, GPS devices, social media, and even open-government data. The data can be captured through specialized hardware, software, or a combination of both. It is vital to ensure the data collection process is efficient, secure and reliable, as this information is the foundation of the digital twin.

Simulation Models

A digital twin requires a mathematical model that can simulate the behavior of the physical counterpart accurately. These models, called simulation models, can range from simple equations to complex 3D computer simulations covering various physical domains, such as structural mechanics, fluid dynamics, and thermodynamics. These models help to replicate the characteristics, performance, and response of the real-world object in a digital environment.

Simulation models can be built using dedicated software or programming tools, such as MATLAB, Simulink, or ANSYS.

Building a Physical Digital Twin

Building a physical digital twin involves creating a virtual representation of a physical object, system, or process. This digital counterpart can facilitate understanding and predicting the performance, optimizing operations, and offering insights for improvement. In this article, we will discuss five key steps for creating a successful physical digital twin.

Identifying the Target System

The first step in building a digital twin involves identifying the physical system or process that it will represent. This could be an industrial machine, a building, or even a natural environment. At this stage, it’s essential to define the purpose and goals of the digital twin. Typical objectives include predicting and optimizing performance, understanding failure modes, and increasing efficiency.

It is vital to understand each component of the system, their interactions, and functional dependencies. Gathering in-depth knowledge of the system’s design, materials, and operational settings is necessary for creating an accurate and reliable digital twin.

Selecting the Right Sensors and Data Sources

Developing an effective digital twin requires gathering data on the current state and performance of the system. This data is crucial in informing the virtual model and enabling accurate simulations. Therefore, it’s essential to identify and install appropriate sensors throughout the target system.

When choosing sensors, it’s crucial to consider the size, accuracy, placement, and connectivity of the devices, as well as the type of data they measure, such as temperature, pressure, or vibration. Additionally, data sources from existing systems, equipment logs, and environmental sensors should be considered.

Data collected from these sources will need to be processed and analyzed, so integration with data management infrastructure and analytics tools should also be considered.

Developing the Simulation Model

Once data sources are in place and the system’s elements and interactions are understood, the next step is to develop the simulation model. This involves continuously updating the digital representation with real-time data collected from the sensors to create an accurate, live virtual counterpart.

The complexity of the simulation model will depend on the complexity of the target system, with more intricate systems requiring sophisticated mathematical models that capture the underlying physics and interactions.

The simulation model should be validated against real-life observations, ensuring it accurately represents the physical system. This may require iterative refinement to improve its performance.

Implementing AI and Machine Learning Algorithms

To maximize the utility of a digital twin, AI and machine learning algorithms can be implemented to process the sensor data, identify patterns, and develop increasingly accurate predictive models of the system’s behavior over time.

These algorithms learn from the system, updating their models as new data becomes available. This continuous learning allows for better performance predictions and optimization strategies.

Additionally, AI can be used to analyze the system’s response to different input scenarios, allowing operators to test potential changes and interventions without risk to the physical system.

Integrating the Twin into the Existing System

The final step in building a physical digital twin is integrating it with the existing system. This involves connecting the virtual model to relevant operational technology, such as controllers, actuators, and other hardware devices, as well as data management infrastructure for data storage and analysis.

It’s also crucial to ensure that the virtual model and the physical system can communicate seamlessly. This allows for real-time monitoring, control, and optimization of the target system as conditions change.

The integration of the digital twin should be accompanied by user training and adoption support. Operators may need guidance to understand how to use the digital twin effectively and make the most of the insights and opportunities it presents.

Once the digital twin is integrated, it becomes an essential part of the system’s management and decision-making process.
