Abstract:
A current regulator is provided for an electric machine drive system for driving an electric machine. The current regulator includes an adjustable damping module that has a value of virtual damping resistance that is applied at the current regulator. The value of virtual damping resistance is adjustable as a function of sampling frequency. A controller can control the current regulator by determining whether the sampling frequency has changed since a previous execution cycle of the current regulator, and when the sampling frequency has changed since the previous execution cycle, the controller can modify the damping value as a function of the sampling frequency to allow the damping value to change with the sampling frequency. The damping value has a new value of virtual damping resistance that is applied at the current regulator after modifying the damping value. The controller can then execute the current regulator in accordance with the modified damping value to generate the voltage commands.

Claim (Index 1):
A method for controlling a current regulator of an electric machine drive system for driving an electric machine, the method comprising:\n determining, at a controller, whether a sampling frequency has changed since a previous execution cycle of the current regulator; storing a previous damping value that is a previous value of the virtual damping resistance applied during the previous execution cycle of the current regulator; modifying, at the controller when the sampling frequency has changed since the previous execution cycle, a damping value of the current regulator as a function of sampling frequency to allow the damping value to change with the sampling frequency, wherein the damping value has a new value of virtual damping resistance that is applied at the current regulator after modifying, wherein the modifying comprises: determining the modified damping value based on the sampling frequency during a current execution cycle of the current regulator, wherein the modified damping value is a new value of virtual damping resistance based on a new sample frequency; computing a change in damping value based on the difference between the modified damping value and the previous damping value, wherein the change in the damping value is a change in the virtual damping resistance based on a difference between the new value of virtual damping resistance and the previous value of virtual damping resistance; and executing the current regulator to generate voltage commands in accordance with the modified damping value.
