- The speed PI controller has gains of P = 0.2785 and I = 2.678.
- The d-axis current PI controller has gains of P = 5.135 and I = 8663.
- The q-axis current PI controller has gains of P = 4.59 and I = 8026.
The same velocity commands are applied before and after the autotuning process. Plot
the speed responses before and after the controllers are tuned using the Closed-Loop PID
Autotuner block. The speed response curves are aligned in time to compare controller
performances side-by-side.

After tuning the controllers, the speed response of the AC motor has a faster transient
response and smaller steady-state error.
