用最佳旋转轴方法形成误差信号的飞行器姿态控制系统

 本文重点讨论采用所谓最佳旋转轴方法来形成飞行器纵轴指向控制的误差信号,对于绕飞行器纵轴本身转动的控制主要讨论了滚动稳定和倾斜稳定两种情况下误差信号的形成。详细推导了它们的计算公式。作为这个方法应用的例子,我们还讨论了如果飞行器上安装一个三轴平台或一组捷联式速率陀螺时,怎样由它们敏感的信号形成姿态控制误差信号,并给出了相应的姿态控制系统原理结构图。

A VEHICLE ATTITUDE CONTROL SYSTEM FORMING THE ERROR SIGNAL BY WAY OF THE OPTIMAL ROTATION AXIS

This paper deals with a method forming the error signal to control the direction of the longitudinal axis of a vehicle by way of the optimal rotation axis. In order to control rotation around the longitudinal axis, the ways to form the error signals in the case of roll stability and slope stability are considered. The analytical formulae are developed in detail. As examples of application of this method we have also discussed how to form the error signals sensored by a three gimbal platform or a group of stra-pdown rate gyros mounted in the vehicle. Corresponding block diagrams are presented.
