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

Introduction
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 airconditioning 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 constants. There are 3 main control loops...
