Abstract: The present invention relates to control of a wind turbine where a torque limit is set on a control signal. A current torque value of a rotor of the wind turbine is determined and compared to an upper torque limit value and the control signal is modified if the current torque value is larger than the upper torque limit value. The upper torque limit value is based on a lower envelope signal which tracks the current torque value if the current torque value is lower than or equal to the previous lower envelope value and is set as a rising signal if the current torque value is higher than the previous lower envelope value. The upper torque limit is set to be a first amount higher than the lower envelope signal.

Abstract: The invention provides a method of controlling operation of a wind turbine having a tower. The method includes determining an overall control output including lateral oscillation control for dampening lateral oscillation of the tower, and using the overall control output to control wind turbine operation. The method further includes receiving lateral oscillation sensor data indicative of a level of lateral oscillation of the tower, determining a rated lateral oscillation control output in dependence on the received lateral oscillation data, and receiving an indication of yaw error of the wind turbine. A lateral oscillation control output included in the overall control output is determined to be de-rated from the rated lateral oscillation control output when the indicated yaw error is above a predetermined lower threshold level.
