Abstract

The invention discloses an inertia system angle perturbation measuring device and application of the device. The device consists of 12 linear acceleration sensors which form 6 measuring units in pairs; each measuring unit is provided with 2 linear acceleration sensors which are installed on the same plane; the sensitive axes of the 2 linear acceleration sensors are in parallel, and the sensitive center connecting lines are vertical to the sensitive axes of the 2 linear acceleration sensors; every two measuring units are as one group; the angle between the sensitive center connecting lines of the 2 measuring units in each group is 90 degrees; in addition, 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; the measuring units in pairs are respectively installed on three space planes which are mutually vertical. The sensitive centers of the three linear acceleration sensors on the same straight line are positioned on the intersection line of the space plane on which the sensors are installed and the space plane on which another group of measuring units are installed. The invention has the advantages of high measuring speed, small size and good reliability.

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. 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 (attenuation to about 10%, reaching 3mrad) has always been different from tha...
