Development of a Load Condition Analysis Framework for Domain Adaptation between Digital Twin and Measured Current

Key Points

• The aim is to analyze load variations in three-phase induction motors using digital twin simulations and current signals.
• Analyzed load variations in shot blast equipment's induction motor through current signals.
• Developed reference operating points for load rates from 0-120% in digital twin simulations.
• Conducted domain adaptation analysis using MATLAB/Simulink based framework.
• DANN achieved the highest silhouette coefficient of 0.38 and a balanced mean difference of 0.69 in actual data.
• Soft ratio analysis demonstrated maximum similarity at 40%, highlighting its significance in sensitivity to load conditions.
