摘　　要：两轴四环架稳定是一种高精度的陀螺稳定方案,广泛应用于机载光电侦察吊舱等侦察监视设备中。分析了两轴四环架稳定平台的主要扰动源及其对系统的影响,根据多框架光电稳定平台的结构推导出各框架的运动学耦合方程,并且分析了该光电稳定平台在抗扰性能方面的主要优点。对两轴四环架系统控制模型的仿真计算表明两轴四环架稳定系统的稳定精度为0.04mrad。Four-gimbal two-axis gyro-stabilized platform is widely used in military reconnaissance and surveillance system, such as airborne electro-optical reconnaissance pod. The main interference source and its effects on the system are analyzed. The kinematics-coupled equation of each frame is derived from the structure of multi-frame electro-optical stabilized platform. And the advantage in the antiinterference performance of multi-frame electro-optical platform is analyzed. A control model of the four-gimbal two-axis gyro-stabilized platform is built, and the simulation result indicates that the stabilization accuracy is 0. 04 mrad.
