摘要: Hybrid dynamic systems (HDS) combine both discrete and continuous dynamics. Discretely controlled (DCCS) is an important class of HDS in which the system switches between several modes response to control events issued by a controller. Their dynamics depend on mode is. Wind turbine converters are example DCCS. Faults may impact significantly availability production performance wind turbines. These faults can occur as gradual abnormal change values parameters describing mode. In this case, they entail drift operating conditions until failure takes over completely. Detecting early stage allows reducing power losses well unavailability maintenance costs. However, be observed only when where described affected active. Consequently, paper proposes approach based use hybrid classifier able monitor normal converter impacted parametric fault. This keeping useful patterns representative therefore detect it its stage.
