What I built
Duel Dyno compares fixed duty and PI control under the same load step. Pit Tuning shows the effect of gain changes on RPM error, overshoot and recovery time. Each run exports 401 simulated samples.
What I verified
For a 65% load step, the Redam lonjakan preset reduced peak overshoot from 487 to 263 RPM against the default PI settings. The measured mean absolute RPM error fell from 97 to 72 RPM in the same 10-second simulation, while settling time increased slightly from 2.95 s to 3.10 s under the damped gain tradeoff.
The model checks and Anatomy geometry audits passed. I verified the tuning controls and CSV export in a desktop browser and the layout at 390 px.
Model assumptions
The first-order model uses illustrative motor parameters and a speed-dependent load. All RPM and voltage readings are simulated.
