Abstract
A method for controlling an electrical converter is disclosed. First, an average flux reference is determined from a reference torque and an estimated torque. At least one difference flux reference is determined from at least one difference current reference. A winding flux reference for each winding system is determined from the average flux reference and the at least one difference flux reference by adding and/or subtracting the at least one difference flux reference to the average flux reference. Switching commands for each converter branch are determined from the winding flux reference and an estimated winding flux for the winding system, which is connected to the respective converter branch. The winding flux reference and the estimated winding flux are provided to a dedicated model predictive controller for the respective converter branch, which determines the switching commands; and applying the switching commands to each converter branch.
