Abstract: An inverter electrically operatively connected to an electric machine and in communication with a controller is described. The inverter is electrically connected to a high-voltage DC power bus. A method for controlling the multi-phase inverter circuit includes monitoring, via the controller, a rotational speed of the electric machine during operation of the inverter in an over-modulation mode. The inverter is commanded to operate in a linear modulation mode when the rotational speed is within a speed range associated with objectionable audible noise generated by operating the electric machine in the over-modulation mode.

A method for controlling the electric machine includes monitoring rotational position of the electric machine, and periodically executing a speed observer to determine a rotational speed of the electric machine based upon the monitored rotational position of the electric machine. An acceleration observer is periodically executed to determine an acceleration rate, wherein the acceleration rate is determined based upon a time-based change in the rotational speed of the electric machine. A virtual inertia term is determined based upon the acceleration rate, and a torque compensation term is determined based upon the virtual inertia term and the acceleration rate.

The one of the switches is controlled employing the intermediate duty command and the aligned carrier.

Abstract: A torque system includes a DC power device, a polyphase electric machine, a contactor pair, a power inverter module (PIM), and a controller. The PIM connects to the power device via the contactor pair and directly connects to the electric machine. The controller executes a method to control a fault response under a fault condition resulting in opening of the contactor pair and a polyphase short condition. The controller calculates a back EMF of the electric machine and transmits switching control signals to semiconductor switches of the PIM to transition from the polyphase short condition to a polyphase open condition only when the calculated back EMF is less than a calibrated value and a voltage rise on a DC side of the PIM is less than a calibrated voltage rise. A vehicle includes the DC power device, road wheels, electric machine, PIM, and controller.

Abstract: A method for controlling an electrically-powered torque machine of a powertrain system includes determining a predicted torque command to control the torque machine. A flux command is determined responsive to the predicted torque command. The flux command is a flux level providing a fast torque reserve that is responsive to the predicted torque command. The fast torque reserve is a prescribed minimum rate of change in torque output from the torque machine responsive to the predicted torque command. An inverter controller controls flux of the torque machine responsive to the flux command.

Abstract: A voltage source inverter controller for controlling an inverter electrically connected to an electric machine includes a current command generator, a six-step flux controller and a current regulator. The six-step flux controller generates a flux modifier to regulate flux in a flux-weakening speed/load operating region of the electric machine when operating the electric machine in a six-step mode. The current command generator converts a desired torque to three-phase desired currents that are input to a dq0-dq transformer and combined with the flux modifier to determine a modified-flux direct-quadrature (dq) current request. The current regulator includes a proportional-integral feedback controller, anti-windup elements, a dq voltage limit element and a voltage magnitude limiter. The proportional-integral feedback controller and the anti-windup elements perform closed-loop current control on the modified-flux dq current request to determine commanded dq voltages.
