Abstract
Methods and systems are provided for controlling an electric machine via an inverter while compensating for one or more hardware delays. The method includes receiving a control signal, producing a first sampling signal based on the control signal, and adjusting the sampling signal to compensate for a first delay of the one or more hardware delays. The inverter is operable to produce a voltage signal based on the control signal, and the electric machine is operable to produce a current based on the voltage signal. A sampling of the current is performed based on the first sampling signal.
