Pitch control system for pitching wind turbine blade

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:

• controlling a main pitch force subsystem of the pitch force system, the main pitch force subsystem being capable of applying a main pitch force to the blade,
• controlling an auxiliary pitch force subsystem of the pitch force system, the auxiliary pitch force subsystem being capable of applying an auxiliary pitch force to the blade in addition to the main pitch force,
• wherein the pitch control system in a decision mode is arranged for
• deciding whether or not to activate the auxiliary pitch force subsystem and apply the auxiliary pitch force to the blade,
• activating the auxiliary pitch force subsystem for applying the auxiliary pitch force to the blade if it is decided to activate the auxiliary pitch force subsystem and apply the auxiliary pitch force to the blade, wherein the activating is initiated at an initiation point in time where the main pitch force is sufficient to pitch the blade into a target pitch value corresponding to the initiation point in time.
