四环式两轴稳定平台闭锁环控制系统设计与应用

四环式两轴稳定是一种高精度的陀螺稳定方案,广泛应用于机载光电吊舱等侦察监视设备中。本文提出一种四环式两轴稳定平台闭锁环失稳的解决方案。为分析此方法的性能,给出了精确分析模型。结果表明,与传统的控制方式相比,对稳定平台实施改进型的控制策略,能够在不改变稳定平台硬件的前提下,将系统的动态性能和静态性能提高10%。

Design and Application of Control System for Atresia Frame of Four-Gimbal Two-Axis Gyro-Stabilized Platform

Four-gimbal two-axis gyro-stabilized platform is widely used in military reconnaissance and surveillance system,such as airborne electro-optical reconnaissance pod.A method to keep up the stability of atresia frame of four-gimbal two-axis gyro-stabilized platform is presented.Mathematical model for precision analysis is formulated to evaluate the performance of the presented approach.A contrast is given to test the effectiveness of the method.The experiment results show that the stability of atresia frame is improved by 10% in the improved control without changing the hardware of the system.
