Abstract: Described embodiments relate to motor control for synchronous motors, and more specifically, some embodiments relate to motor-current control for permanent-magnet synchronous motors. Embodiments of a current controller are described that include an adaptive controller configured to adapt to changing system dynamics of a PMSM. Embodiments of adaptive control techniques are described that involve estimating system parameters of a PMSM and adapting control actions to compensate for such estimated system parameters. Such adapted control actions may be expected to track an observed motor current to a desired motor current. Systems, methods and devices related to the above are also described.
