Simulation results show that, in the closed-loop system, precise attitude control is accomplished in spite of the uncertainties and external disturbances in the system.
仿真结果表明：即使系统存在不确定性和外界干扰，仍可在闭环系统中实现精确的姿态控制。

In stabilizing and tracking system of optoelectronic platform, a stabilizing controlloop must be designed firstly because of various external disturbances.
机载光电平台稳定与跟踪系统由于受到外部各种干扰的影响，需要首先建立一个稳定控制回路。
