The invention relates to an independent feathering control system and a control method for a wind driven generating set, wherein the control system comprises a sampling module, a control module and a driving module. A feathering motor in the driving module is connected with the blades of the wind driven generating set through a speed reducer. The sampling module is used to acquire the signals such as the wind driven generating set power, the boss rotating speed, the impeller position, the feathering angle, the paddle vibration, and the like, and to respectively send the acquired signals to the control module. The control module comprises a wind machine power controller for processing the wind driven generating set power signal and the boss rotating speed signal, a periodic unbalanced load compensation controller for processing the impeller position signal, the wind machine power signal and the boss rotating speed signal, a transient state impact load compensation controller for processing the feathering angle signal, the paddle vibration signal, the impeller position signal, the wind machine power signal and the boss rotating speed signal, and an output coupler for processing the signals outputted from the three controllers and comprehensively outputting the signals to the driving module.
