DC & AC Electric Drive Control
Reproducible MATLAB/Simulink studies of DC motor control and induction-motor indirect field-oriented control.
This project studies closed-loop speed and torque control for an armature-controlled DC motor and a three-phase squirrel-cage induction motor using indirect field-oriented control.
I built authoritative models in MATLAB R2025b and Simulink, with averaged converter and inverter stages because Simscape Electrical was unavailable in the working environment. A separate NumPy/SciPy implementation provides an independent numerical check for the DC response.
Reproducible experiment set
Six cases cover no-load speed steps, load-torque disturbance rejection, and torque or current-command tracking for both machines. Each run exports time histories, plots, and metrics including rise time, settling time, overshoot, steady-state error, peak current, torque ripple, and recovery behavior.
The repository keeps model generation, simulation scripts, generated .slx files, CSV outputs, figures, and the LaTeX report together. One command rebuilds the models and evidence, making the report a reproducible engineering artifact rather than a collection of manually copied screenshots.
