Abstract: Digital twin models can combine mathematical models and describe dynamics of machines visually in details. Control mechanism can be designed and planned based on such models by considering the overall machine performance and machines operation. Therefore, machine design can be optimized accordingly in terms of the standards on effectiveness, efficiency and safety. In a long run, real-time condition monitoring on machines can be achieved by employing a digital twin which ensures the accuracy of the diagnosis as well as reduces time consuming process and the need of professional knowledge. The research in this paper presents a development method of digital twin model for cart-pendulum systems which is based on MATLAB/Simulink Multi-body simulation. The effectiveness of the modeling method is verified in test platform.
