MULTICORE IMPLEMENTED WEIGHT-FUNCTION BASED PREDICTIVE CONTROL OF AN ELECTRIC CONVERTER

摘要

A method for controlling an electrical converter 12 comprises the steps of: receiving an actual switching state u k-1 of the electrical converter 12; determining a scenario tree 50 for possible future switching states of the electrical converter 12 based on the actual switching state u k-1 , the scenario tree 50 defining a plurality of possible future switching sequences, a switching sequence U being defined by a path from a root node 52 of the scenario tree 50 to a leave node 58 of the scenario tree 50; calculating a weight w for a switching sequence by evaluating nodes 60 of the scenario tree 50; and determining the next switching state u k to be applied to the electrical converter 12 from a switching sequence with a best weight. The evaluation of the nodes 60 is performed by at least two processor cores 30a, 30b, 30c, 30d.
