N2 - The standard material fatigue estimation process is implemented in an Economic Nonlinear Model Predictive Controller. The process comprises cycle identification, mean-stress effect, Wöhler curves and Linear Damage Accumulation. For cycle identification, this novel implementation uses a standard Rainflow-algorithm which is substituted periodically by linear functions based on its output. The implementation is compared to two straightforward methods for fatigue penalization using a wind turbine model and exhibits higher profit over the entire range of tested reference wind velocities.
