This application note describes how to tune the embedded control loops on the
IRMCF3xx series of control IC’s. This covers the IRMCF312, IRMCF311 and
IRMCF343 digital control IC’s for air-conditioning systems and the IRMCF341 IC
for washing machine applications. The control loops include the ID and IQ current
control loops, the velocity control loop, the field weakening loop, IPM control and
bus voltage protection. The note describes the equations used to derive the
control loop constants and experimental methods to tune control constant
