Course record
Motor Control
I use my PSIM report and PI calculation file to revisit the DC-motor model, cascaded current-speed loops, and field weakening.
Unit numbers follow the control structure in the saved design files and do not claim attendance weeks.

How I use this hub
I open one unit at a time, restate the core terms, and compare equations, circuits, code, and saved results.
