Aerospace Instrument-Making Annotation << Back THE FlYWHEEL GYROSTABILIZER OF THE QUADCOPTER ANGULAR POSITION V.V. Fateev, A.V. Kuleshov, A.V. Polynkov The article presents a way of developing the indicator flywheel gyro stabilizer of the quadcopter. Using of additional body – a flywheel – allows to arrange stabi-lizing system in which the primary stabilizing moment is created by the interac-tion of the flywheel and gyrostabilizer platform and unloading moment of the fly-wheel is formed with the help of the additional feedback by flywheel speed. This gives possibility to obtain high feedback steepness of the stabilization channel and thus high accuracy of stabilization, as between the platform and the flywheel are practically no non-rigid elements in the chain of transfer the moment, and nonrigidity in the lowspeed unloading circuit do not have a significant impact on the stability and accuracy of the gyrostabilizer. The paper presents a mathematical model of a uniaxial indicator flywheel gyrostabilizer of the quadcopter in analytical and graphical form, the results of research of stability and accuracy, indicated requirements to the parameters and elements gyrostabilizer. Keywords: indicator gyrostabilizer, flywheel stabilizer, flywheel, quadcopter, the unloading system. Contacts: E-mail: akul1974@mail.ru Pp. 11-17.
