Abstract
A wind turbine control unit includes an upsampling module that receives a first control signal that includes a current control sample value and a predicted control trajectory. The upsampling module also calculates a second control signal in dependence on the current control sample value and the predicted control trajectory. The second control signal has a higher frequency than the first control signal. The upsampling module further outputs the second control signal for controlling an actuator.

A wind turbine control unit comprising an upsampling module configured to:
- receive a first control signal comprising a current control sample value and a predicted control trajectory;
- calculate a second control signal in dependence on the current control sample value and the predicted control trajectory, wherein the second control signal has a higher frequency than the first control signal;
- and
- output the second control signal for controlling an actuator.
A method comprising:
- generating, using a control module of a wind turbine, a first control signal comprising a current control sample value and a predicted control trajectory;
- calculating, using an upsampling module of the control module, a second control signal in dependence on the current control sample value and the predicted control trajectory, wherein the second control signal has a higher frequency than the first control signal;
- and
- outputting the second control signal for controlling an actuator.
A computer program product at least one of downloadable from a communications network and stored on a machine readable medium, comprising program code instructions for performing an operation when executed on a computer process, wherein the operation comprises:
- generating, using a control module of a wind turbine, a first control signal comprising a current control sample value and a predicted control trajectory;
- calculating, using an upsampling module of the control module, a second control signal in dependence on the current control sample value and the predicted control trajectory, wherein the second control signal has a higher frequency than the first control signal;
- and
- outputting the second control signal for controlling an actuator.
