The angular rate gyro is composed of a bell-shaped vibrator, a vibrator fixation shaft, a vibrator pedestal, an airtight enclosure, a shell and a system circuit. The bell-shaped vibrator comprises: a bell shoulder, which has a hemispherical shell structure; a bell waist, which has a ...
The new ADXRS150 and ADXRS300 gyros from Analog Devices, with full-scale ranges of 150°/s and 300°/s, represent a quantum jump in gyro technology. The first commercially available surface-micromachined angular rate sensors with integrated electronics, they are smaller—with lower power consumptio...
Principle of Gyro Sensors ② Utilizes the Coriolis force acting in a direction perpendicular to the vibration when the angular rate ω is added to mass m vibrating at a speed of V. Coriolis force The Coriolis force is perpendicular to the direction of the reciprocating movement of the pendulum...
GyroWheel is an integrated device that can provide three-axis control torques and two-axis angular rate sensing for small spacecrafts. Large tilt angle of its rotor and de-tuned spin rate lead to a complex and non-linear dynamics as well as difficulties in measuring angular rates. In this pa...
摘要: An extended Kalman filtering technique is addressed for gyroless spacecraft to estimate the angular rate and attitude vectors of spacecraft and the alignment of reaction wheels using only vector...关键词: Angular rate estimation extended Kalman filter gyroless spacecraft misalignment of reaction...
This article focuses on a hemispherical resonator gyro driven by the Coriolis effect. A hemispherical shell, called a resonator, is maintained in the resonance state by amplitude control and phase locking control. Parametric excitation has been used to control the amplitude. For rate measurement mode...
7.The invention discloses a simulating space sailboard torsional vibration control device and a method based on an angular rate gyro. 本发明公开了基于速率陀螺的模拟太空帆板扭振控制装置与方法。 8.This criterion is reasonable because it is not expressed in terms of the precessional velocity, but ...
The bell-shaped vibratory angular rate gyro (abbreviated as BVG) is a novel shell vibratory gyroscope, which is inspired by the Chinese traditional bell. It sensitizes angular velocity through the standing wave precession effect. The bel... Liu,Ning,Su,... 被引量: 27发表: 2013年 Millimeter-...
A gyrowheel (GW) is a kind of electronic electric-mechanical servo system, which can be applied to a spacecraft attitude control system (ACS) as both an actuator and a sensor simultaneously. In order to solve the problem of two-dimensional spacecraft angular rate sensing as a GW outputting...
because thisactionreduces the moment of inertiaIwhile the productIω, the skater’s angular momentum, remains constant. Because of the conservation of direction as well as magnitude, a spinning gyrocompass in an airplane remains fixed in its orientation, independent of the motion of the airplane....
