In wind farms, wake interaction leads to losses in power capture and\naccelerated structural degradation when compared to freestanding turbines. One\nmethod to reduce wake losses is by misaligning the rotor with the incoming flow\nusing its yaw actuator, thereby laterally deflecting the wake away from\ndownstream turbines. However, this demands an accurate and computationally\ntractable model of the wind farm dynamics. This problem calls for a closed-loop\nsolution. This tutorial paper fills the scientific gap by demonstrating the\nfull closed-loop controller synthesis cycle using a steady-state surrogate\nmodel. Furthermore, a novel, computationally efficient and modular\ncommunication interface is presented that enables researchers to\nstraight-forwardly test their control algorithms in large-eddy simulations.\nHigh-fidelity simulations of a 9-turbine farm show a power production increase\nof up to 11% using the proposed closed-loop controller compared to traditional,\ngreedy wind farm operation.\n
