Dataset for an end-to-end open-source DC motor control workflow: current calibration, system identification, and controller validation

The dataset contains 14 raw acquisition logs with more than 60,000 sample rows and a common 10-column structure that records reference commands, measured speed, loop interval, raw and filtered current-sense values, PWM actuation, and synchronized digital multimeter current measurements when enabled.

The experiments cover current-sense calibration, static PWM-to-speed characterization, APRBS-based system identification at 2 ms, 10 ms, 20 ms and 50 ms sampling times, continuous PI controller validation at 5 ms, 10 ms, 20 ms, and 50 ms loop times, three discrete controller validation cases, and an additional chirp-excitation run. MATLAB scripts, model-result tables, processed MAT files, screenshots, and exported figures are included with the raw logs.
