ECE student passionate about power electronics, motor control, and PCB design. Curious about how things work—and how to build them better.

Can anyone help debug my FOC model in MATLAB/Simulink?

SVPWM Stateflow reports unreachable junctions, then a sector-output dimension error. Also seeing precision loss for Kp_c=1.1 as single.

Diagram attached. What should I check first?

Designing a 28V → 12V buck for a power-electronics lab build.

Topology is classic synchronous buck — the real work is compensation, inductor selection, and keeping efficiency up from light load to full load.

Tuning the loop next; will share Bode / load-step results when I have them.

Building field-oriented control (FOC) for a permanent-magnet sync motor in MATLAB/Simulink.

Pipeline: measured ia/ib + rotor angle → Clarke/Park to id/iq → PI current loops from torque refs → inverse Park → SVPWM duty cycles for the inverter.

3rd-year ECE. Building in public.

Right now:
• FOC for a PMSM in MATLAB/Simulink (Clarke/Park → id/iq → SVPWM)
• High-speed carrier PCB for LattePanda MU
• 28V→12V buck — loop design + efficiency

Power electronics + control. Sharing what I learn as I go.
