Method and system for predictive control of a wind turbine

A method of controlling a wind turbine having a plurality of wind turbine actuators, the method comprising the following steps:

• receiving operational data of the wind turbine;
• based on the received operational data, estimating an operational state of the wind turbine;
• using a control model to predict potential operational states of the wind turbine depending on operation of the wind turbine actuators over a finite period of time,
• wherein the control model comprises a predictive aeroelastic control model to determine primary loads based on the received operational data,
• the control model further comprising a strength calculation module to calculate one or more secondary load parameters based on one or more of the primary loads, constraints being defined for the one or more secondary load parameters, the one or more secondary load parameters comprising at least one of the following:
• a force, a moment, a stress, or a strain;
• optimizing a cost function over a finite optimization period of time, subject to the constraints, to determine an optimum trajectory comprising commands for the wind turbine actuators;
• and
• using the first commands of the determined optimum trajectory to control the wind turbine actuators.
