A wind turbine generator system, and a control method, controller and control system therefor. The control method for a wind turbine generator system comprises: monitoring wind resource data of the location of a wind turbine generator system, and operation data of the wind turbine generator system; identifying a complex wind condition according to the wind resource data and the operation data; determining the cumulative time ratio of the complex wind condition occurring within a first predetermined time period; and in response to the cumulative time ratio exceeding a first preset threshold value, controlling the wind turbine generator system to perform a protection operation. The present invention can effectively reduce fatigue accumulation of a wind turbine generator system, reduce the operation risk thereof, ensure the safe working of the wind turbine generator system under a complex wind condition, and improve the adaptability of the wind turbine generator system to complex wind conditions.
