MUMBAI, India, July 5 -- Intellectual Property India has published a patent application (202517058459 A) filed by Vestas Wind Systems A/S, Aarhus, Denmark, on June 18, for 'controlling the pitch angle of a rotor blade of a wind turbine.'

Inventor(s) include Jeppesen, Christian; Schwensen, John; and Spagnolo, Fabio.

The application for the patent was published on July 4, under issue no. 27/2025.

According to the abstract released by the Intellectual Property India: "The invention provides a method for controlling a pitch angle of a rotor blade (6) of a wind turbine (1) with a hydraulic pitch actuator system (200). The method comprises a step of receiving a current pitch signal of the rotor blade (6) and a pitch reference signal indicating a desired pitch angle for the rotor blade (6), a step of receiving an operating parameter signal (63) from the hydraulic pitch actuator system (200), a step of generating a feedback signal based on the operating parameter signal (63), a step of using a gain scheduler (150) to provide a variable feedback gain, a step of generating a damping signal based on the feedback signal and the variable feedback gain, a step of generating a pitch control command based on a difference between the current pitch signal and the pitch reference signal, and on the damping signal, and a step of sending the pitch control command to the hydraulic pitch actuator system (200)."

The patent application was internationally filed on Nov. 30, 2023, under International application No.PCT/DK2023/050291.
