Abstract: A control arrangement for controlling an electronic device, is provided. The control arrangement comprises: an inner controller being coupled to the electronic device and being configured for generating at least one control signal for controlling the electronic device depending on at least one instruction signal from an outer controller; and a smart controller coupled to the inner controller and being configured for providing at least one substitute instruction signal for controlling the electronic device to the inner controller if an abnormality related to a signal traffic between the inner controller and the outer controller is detected.

Abstract: A method for controlling a three-phase electrical converter including: selecting a three-phase optimized pulse pattern from a table of pre-computed optimized pulse patterns based on a reference flux; determining a two-component optimal flux from the optimized pulse pattern and determine a one-component optimal third variable; determining a two-component flux error from a difference of the optimal flux and an estimated flux estimated based on measurements in the electrical converter; determining a one-component third variable error from a difference of the optimal third variable and an estimated third variable; modifying the optimized pulse pattern by time-shifting switching instants of the optimized pulse pattern such that a cost function depending on the time-shifts is minimized, wherein the cost function aincludes a flux error term and a third variable error term, wherein the flux error term is based on a difference of the flux error and a flux correction function providing a flux correction based on the time-shifts and the third variable error term is based on a difference of the third variable error and a third variable correction function providing a third variable correction based on the time-shifts; and applying the modified optimized pulse pattern to the electrical converter.
