Abstract
A floating frame controller determines a current Park vector, selects a reference frame for the current Park vector, and adjusts the reference frame until a quadrature component of a current Park vector in the adjusted reference frame is equal to a predetermined value, whereby a synchronous reference is established. The synchronous frame is used to control a power converter. The floating frame controller can drive a synchronous machine without the use of rotor position sensors.
