Original Abstract Submitted
A method for controlling an electrical converter for driving an electrical machine comprises the steps of: estimating a stator flux vector depending on at least one measurement in the electrical converter; determining an optimized pulse pattern for the electrical converter depending on a reference angular stator frequency; determining a reference stator angle of the stator flux vector depending on the reference angular stator frequency; determining a reference stator flux vector depending on the optimized pulse pattern and the reference stator angle; determining a difference between the reference stator flux vector and the estimated stator flux vector; modifying switching instants of the optimized pulse pattern, such that the difference is minimized; and applying at least a part of the modified optimized pulse pattern to the electrical converter.
