Sliding mode sensorless control model of hub motor based on digital twin technology

Abstract

Abstract This paper introduces a novel integration of sliding mode control and digital twin technology to develop a sensorless control model for hub motors. The proposed approach overcomes the limitations of traditional methods, such as the inability to pre-evaluate parameter changes and the lack of multidimensional monitoring and interaction analysis. The constructed model enables real-time simulation that closely reflects actual motor behavior, allowing precise tuning and validation of control parameters. Simulation results show that the system achieves rapid response, robust performance under varying load and speed conditions, and superior adaptability compared to existing methods. These advancements highlight the potential of this approach for precise and robust motor control in robotics and autonomous vehicles.
