A high-precision three-floating gyroscope active magnetic levitation system

Abstract

The invention relates to a high-precision three-floating gyroscope active magnetic suspension system. The system comprises an electromagnetic element part, an input signal conditioning SIP module, a central processing circuit SOC module and an output signal conditioning SIP module; the electromagnetic element part is used for limiting, detecting and adjusting the degrees of freedom of floaters; the input signal conditioning SIP module and the electromagnetic element part form a L-R bridge, and is used for extracting the degrees of freedom information of the floaters, and conditioning and converting the information into digital signals, transmitting the digital signals to the central processing circuit SOC module; the central processing circuit SOC module compares the received digital signals with the target position, and the deviation size and direction corresponding to each degree of freedom are calculated, and the size and direction of the adjusting current are calculated and outputaccording to the deviation size and direction; the output signal conditioning SIP module loads the received adjusting current to the corresponding excitation winding of the electromagnetic element. According to the system, the problem that in the prior art, an active magnetic suspension gyroscope is low in precision is solved, the blank of the field of the high-precision three-floating gyroscope active magnetic suspension system is filled up.

Description

technical field [0001] The invention relates to a three-float gyroscope, in particular to an active magnetic levitation system for a high-precision three-float gyroscope. Background technique [0002] The three-float gyroscope is the development and improvement of the single-degree-of-freedom liquid floating integral gyroscope. The dynamic pressure air bearing motor is used instead of the ball bearing motor, and the magnetic levitation technology is used to eliminate the mechanical friction torque, which improves the life and accuracy of the gyroscope. The structure is shown in figure 1 . Because the buoy adopts liquid floating technology, the gyro motor adopts dynamic pressure air floating technology, and the output shaft adopts magnetic levitation technology, it is referred to as the three-float gyroscope for short. The three-floor gyroscope has high precision and is usually used in fields such as manned spaceflight and space exploration that require very high gyroscope p...
