Abstract: Methods, systems and apparatus are provided for generating voltage commands used to control operation of a permanent magnet machine. For example, a control system is provided that generates voltage command signals for controlling a permanent magnet machine during a transition from an initial operating condition to a final operating condition. The control system includes a processor configured to execute software instructions, and a memory configured to store software instructions accessible by the processor. The software instructions comprise a voltage command generator module. Based on an electrical angular frequency of the permanent magnet machine, and synchronous reference frame current signals, the voltage command generator module is configured to generate ramped voltage command signals that each change linearly in accordance with a slope during a transition period that is set to a rise time.

Abstract: A method for monitoring an inverter module for a multi-phase electric motor/generator includes deactivating operation of the inverter module, monitoring voltage on a high-voltage bus configured to supply electric power to the inverter module, detecting occurrence of a true fault when a change in the voltage on the high-voltage bus is greater than a predetermined threshold, and detecting occurrence of a false fault when the change in the voltage on the high-voltage bus is less than the predetermined threshold.
