11.2: Current Loop Auto Tune
Tune the Current Loop with Auto Tune
METHOD: The current loop Auto Tune algorithm applies a square-wave command to the
current loop and adjusts current loop proportional gain (Cp) and current loop integral
gain (Ci) until a desirable waveform is obtained.
Initial current loop proportional gain (Cp) and current loop integral gain (Ci) values can
be calculated with The Calculate Function (p. 54).
