Title:
BLADE CONTROL SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/104504
Kind Code:
A1
Abstract:
A blade control system (100) and method. The control system (100) comprises an electric motor (110), an electric motor control module (120), a real-time clock (130) and a calculation module (140), wherein the calculation module (140) calculates an incident angle according to time data, determines an angle to be rotated and transmits the angle to be rotated to the electric motor control module (120) so as to control the electric motor (110) to drive blades to rotate by the angle. The control method comprises calculating the incident angle according to blade position and orientation and the time data, determining the angle to be rotated, and controlling the blades to rotate by the angle. Real-time control enables angle control of the blades to be more accurate.
