S. - Wind turbines equipped with fractional-order controllers: Stress on the mechanical drive train due to a converter control malfunction. Wind Energy. ISSN 1095-4244. Vol. 14, n.º1 (2011) p. 13-25.1095-4244http://hdl.handle.net/10400.21/2259This 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.
