Accurately modeling the hysteresis behavior of hydraulic pitch actuators is crucial for precise blade pitch control because hysteresis introduces inaccuracies and delays in the pitch response, which can negatively impact power regulation, load mitigation, and overall turbine performance. Hydraulic pitch actuators are used to adjust the angle of the wind turbine blades, enabling precise control over power output and rotor speed. Hysteresis is a phenomenon where the output of a system depends not only on the current input but also on its past inputs. In hydraulic pitch actuators, hysteresis arises due to friction in the cylinder, valve overlap, and fluid compressibility. This means that for a given control signal, the actual blade pitch angle will be different depending on whether the actuator is moving in one direction or the other. Inaccurate modeling of hysteresis can....
