Abstract
Provided is a method and controller for controlling a vehicle dc bus voltage. The method includes generating a parameter. The parameter is based on a reference dc bus voltage squared. The method includes controlling the vehicle dc bus voltage based on the parameter and a detected dc bus voltage. The method may also include generating another parameter based on a power demand associated with at least one of a motoring mode operation and a generating mode operation of a traction motor associated with the vehicle. The power demand is indicated in a message received via a dedicated high speed data bus. The method includes controlling the vehicle dc bus voltage based on the another parameter.
