A system for controlling a wind turbine may include at least one sensor configured to provide at least one of a wind speed signal or a wind direction signal and a turbine controller configured to control the operation of the wind turbine. The system may also include a secondary controller inserted between the sensor(s) and the turbine controller. The secondary controller may be separated from the turbine controller by a distance and may be configured to receive the wind speed signal and/or the wind direction signal from the sensor(s) over a communication interface. In addition, the secondary controller may be configured to adjust the wind speed signal and/or wind direction signal based at least in part on a signal bias value(s) to an adjusted signal(s) and to provide the adjusted signal(s) to the turbine controller.
