A method of wake steering a first wind turbine. A second wind turbine is positioned downstream of the first wind turbine so that the second wind turbine can be affected by a wake of the first wind turbine. A yaw offset signal is applied to a yaw control system of the first wind turbine, the yaw offset signal causing the yaw control system to create a yaw offset between a rotor of the first wind turbine and a wind direction, the yaw offset steering the wake away from the second wind turbine. A yaw offset controller is operated to vary the yaw offset signal in response to changes in the wind direction. In response to the detection of the wind direction crossing the full-wake wind direction a timing system is started and the operation of the yaw offset controller is held so that the yaw offset signal does not vary in response to changes in the wind direction. The operation of the yaw offset controller is reinstated in response to either: a timeout of the timing system, or detection of the wind direction re-crossing the full-wake wind direction before timeout of the timing system.

The invention relates to adjusting individual pitch of wind turbine rotor blades. The invention involves receiving a sensor signal indicative of wind turbine tower acceleration, and determining a frequency signal in a fixed coordinate frame of the wind turbine, including 3P frequency content and tower natural frequency content. The invention involves generating a pair of mutually orthogonal signals in the fixed coordinate frame, which includes filtering to retain content corresponding to 2P cyclic pitch and tower natural frequency minus 1P cyclic pitch. The invention involves applying a control action to the orthogonal signals to obtain control signals for mitigating target frequency content in the tower, and applying an inverse m-blade coordinate transformation to the control signals to obtain individual pitch reference offset values for the respective rotor blades. The pitch of the rotor blades is adjusted based on the obtained individual pitch reference offset values.
