Summary:The present subject matter is directed to a system and method 200 for dynamically controlling a wind turbine 10. The method 200 includes operating the wind turbine 10 based on a thrust set point 74 and a speed set point 76. A next step includes determining a desired change in actual speed 75 of the wind turbine 10 in response to control actuations starting from an instantaneous operating point 81. The method 200 also includes determining a desired change in thrust 73 of the wind turbine 10 in response to control actuations starting from the instantaneous operating point 81. Next, the method 200 determines at least one parameter set point that achieves the desired change in speed 75 and the desired change in thrust 73 and controls the wind turbine 10 based on the parameter set point so as to maintain the actual thrust and the actual speed of the wind turbine 10 within a certain tolerance of the thrust set point 74 and the speed set point 76, thereby regulating loads acting on the wind turbine 10 while simultaneously maintaining optimal or near optimal power output.
