This paper is on variable‐speed wind turbines with permanent magnet synchronous generator (PMSG). Three different drive train mass models and three different topologies for the power‐electronic converters are considered. The three different topologies considered are respectively a matrix, a two‐level and a multilevel converter. A novel control strategy, based on fractional‐order controllers, is proposed for the wind turbines. Simulation results are presented to illustrate the behaviour of the wind turbines during a converter control malfunction, considering the fractional‐order controllers. Finally, conclusions are duly drawn. Copyright © 2010 John Wiley & Sons, Ltd.
