Abstract

The invention discloses an inertia system angle perturbation measuring device and application of the device. The measuring device consists of 4 linear acceleration sensors which form 2 measuring units in pairs; the 2 linear acceleration sensors of each measuring unit are installed on the same place with the sensitive axes in parallel and the connecting line of the sensitive centers vertical to the sensitive axes of the 2 linear acceleration sensors; the distance between the sensitive centers of the 2 linear acceleration sensors of each measuring unit is a set value; the angle between the sensitive center connecting lines of the two measuring units is 90 degrees, and the sensitive center of one linear acceleration sensor of a measuring unit and the sensitive centers of the two linear acceleration sensors of another measuring unit are on the same straight line. With high measuring speed and occupation of few controller resources, the invention is very good for real time control to the inertia system and plays a good role in eliminating perturbation of a carrier to the inertia system. The invention is small and light-weighted, has good reliability and can obviously improve the overall performance of the inertia system.

Description

technical field [0001] The invention belongs to the construction technology of precision guidance equipment, in particular to an inertial system angular disturbance measuring device and its application for reducing the disturbance of the carrier aircraft to the inertial system. Background technique [0002] Inertial sensors are widely used in inertial systems such as precision-guided weapons, such as the patent document with the authorized patent No. 200520078794.X. Inertial system control technology is the core technology of weapon precision guidance, and the isolation degree of inertial system from carrier aircraft disturbance is the core performance index of inertial system control. The stability control strategy of rate gyro and angular accelerometer signal feedback control is commonly used in foreign inertial systems. This control strategy is limited by factors such as the domestic component manufacturing process level, and the isolation index of the inertial system (a...
