Methods and system are provided for controlling permanent magnet motor drive systems. The method comprises the steps of adjusting a first current command in response to a first voltage error to produce a first adjusted current, adjusting a second current command in response to a second voltage error to produce a second adjusted current, limiting each of the first and second adjusted current below a maximum current, converting the first adjusted current to a first potential, converting the second current command to a second potential, and supplying the first and second potentials to the permanent magnet motor. The first voltage error is derived from the second current command, and the second voltage error is derived from the first current command.
