Example
3.4.9 Current Loop
Current loop PI parameters for vector control are divided into low‑speed and high‑
speed groups. These parameters can be automatically obtained through auto‑tuning
on all parameters of asynchronous motor and generally do not need to be modified.
The dimension of the current loop integral regulator is integral gain rather than
integral time. A large current loop PI gain may result in oscillation of the entire control
loop. In the case of severe current oscillation or torque fluctuation, manually reduce
the PI proportional gain or integral gain.
