Design studio
Enter Ld, Lq, stator resistance Rs, sampling and inverter switching frequencies, delay and rise-time spec. Get the stability verdict across your speed range, live z-plane pole maps, step responses — and delay-aware gains you can copy as MATLAB or JSON.
- Stability sweep: textbook PI vs delay-aware design
- Parameter-mismatch robustness (L̂/L, T̂d/Td)
- Gains at any scheduling point, exportable
Inside the designs
Begin with the complete sampled drive loop — controller, effective delay, SVPWM/two-level inverter, PMSM and current feedback — then inspect both controllers with live gain values and step-by-step synthesis.
- Hover any block — see its role and live value
- The one feedback path textbook designs are missing
- Every formula with the actual numbers for your motor
Method & verification
Exactly what is computed and how it is checked: exact ZOH discretization with the modulator convention explicit, direct discrete-time pole placement, and an independent scipy verification of every quantity on every release.
- Discretization & gains verified to ~1e-9
- Closed-loop poles cross-checked against numpy
