Abstract

There is provided a pitch control system () for controlling a pitch force system () for pitching a blade () of a wind turbine (), the pitch control system () being arranged for activating () an auxiliary pitch force subsystem () at an initiation point in time where a main pitch force is sufficient to pitch the blade () into a target pitch value. An advantage thereof may be that tracking of a target pitch value may be improved and the impact on the pitch force system () may be reduced. In aspects, there is furthermore presented a hydraulic pitch system (), a wind turbine (), a method and a computer program product.
