Electromechanical coupling-induced torque ripple in metro PMSM traction systems: modulation mechanism and spectrum analysis under wheel-rail excitation data (for ResEng. submission)

Steps to reproduce
Data Collection: The raw simulation data were exported from a Simulink model of a PMSM traction system with electromechanical coupling. Two primary conditions were simulated: with and without wheel-rail excitation. Data Processing: The .mat files contain the complete time-series data. Specific variables (e.g., motor torque, currents) were extracted and saved as .xls files for each figure. Figure Generation: Use the provided MATLAB Live Scripts (.mlx files) to load the corresponding .xls files and generate the plots. For example, run "3-2bdraw_Te.mlx" to reproduce the torque waveform figures. Analysis: The scripts perform basic FFT analysis and plotting as presented in the paper.
