Abstract: A method of controlling operation of a motor drive system includes receiving motor drive data corresponding to a variable frequency drive. The motor drive data includes a plurality of frequency drive input parameters and a plurality of frequency drive output parameters. The method further includes receiving, by a digital variable frequency drive unit, the plurality of frequency drive input parameters. The digital variable frequency drive unit is a real-time operational model of the variable frequency drive. The method further includes generating, by the digital variable frequency drive unit, frequency drive output parameter estimates corresponding to the plurality of frequency drive output parameters. The method also includes controlling operation of the variable frequency drive based on the one or more of the motor drive data, and the frequency drive output parameter estimates.
