摘要：
The invention relates to a wind turbine comprising a rotor including one or more rotor blades, a pitch system for controlling the pitch angle of said one or more rotor blades, said pitch system comprises at least one pitch actuator, a pitch controller for generating pitch actuator control signals and sensor elements for establishing values of pitch performance parameters, and a compensation controller to compensate for disparities between said pitch actuator control signals and said values of pitch performance parameters, according to a control algorithm. The the compensation controller is arranged to adjust parameters of the control algorithm of said compensation controller in dependency of said disparities. Furthermore the invention relates to a method for compensating for disparities in a wind turbine rotor blade pitch system and use of a method.
