Abstract
A method for controlling an induction machine includes: determining a forward path voltage signal based on a command current and using a first set of gain factors; determining an estimated slip speed; determining a feedback path voltage signal based on a measured motor current and using a second set of gain factors, at least one gain factor of the second set including the estimated slip speed; determining a reference voltage signal based on both the forward path voltage signal and the feedback path voltage signal; and commanding, based on the reference voltage signal, an inverter to apply an output voltage to the induction machine and thereby causing an output current to be generated. At least one of the first set and the second set of gain factors is configured to cause a d-axis component to be decoupled from variations of a q-axis component of the output current, and vice-versa.
