平台姿态角信号的采集与处理

The Acquisition and Processing of the Gimbal Angle Signals of Inertial Platforms

惯性平台一般采用双通道旋转变压器作为姿态角传感器,本文详细介绍了这种姿态角信号的采集、处理和系统运用问题。文中提出一种新的姿态角采集接口和粗精姿态角耦合算法,提出了角度量数字表示的标准形式和软件分解器的概念,以解决粗精锁定回路中与姿态角信号有关的一些问题。所有这些方法都经过数字化平台系统的实际使用验证,效果良好。

Inertial platforms often use two-speed vernier resol- ver as their gimbal angle sensor.The acquisition and processing methods of such signals are discussed in this paper.A new computer inter- face for dada aquisition and a new coupling algorithm of coarse data and fine data are developed.In order to solve some special problems in the gimbal positioning Loop,a standard digital expression of angle data and a concept of soft coordinate resolver are presented.ALL the- se methods has been applied in the design of a digital inertial platfofm and the results are satisfactory.
