Abstract. In this paper, a mixed sensitivity
weighting strategy to the design of H? controller for an induction
generator/infinity bus windmill power system is presented. The system controller
is sinthesized by using H? standard controller design techniques. A combinations
of additive and multiplicative uncertainty representation is used to achieve
the robust stability for a wide range of operating conditions. The capability
of the proposed controller to damp out the oscillations of the power and
angular velocity are evaluated in the simulation study.

KONTROLERA ZA ENERGETSKE SISTEME VETRENJAČA
TEŽINSKOM STRATEGIJOM
MEŠANE OSETLJIVOSTI
U ovom radu je prikazana težinska strategija
mešane osetljivosti za projektovanje kontrolera za indukcioni generator/infinity
bus energetski sistem vetrenjača. Kontroler sistema se projektuje korišćenjem
standardnih tehnika projektovanja kontrolera. Kombinacije aditivne i multiplikativne
reprezentacije nesigurnosti koristi se za postizanje robustne stabilnosti
za širok opseg radnih uslova. Mogućnosti predloženog kontrolera da priguši
oscilacije struje i ugaone brzine ocenjene su simulacionom studijom.
