摘　　要：简述了小型惯性控制平台的组成和工作原理,运用动力学原理建立了台体结构模型。研究了各框架间台体平稳性和机械误差对平台的影响。通过采用小型捷联式/GPS组合航姿仪测量技术和控制技术,平台稳定和跟踪效果好,经测试负载能力3 kg,俯仰角摇摆范围-15°^+90°,方位角范围0~360°,水平姿态精度<0.2°,航向精度<0.3°。The structures and principle of a miniaturized inertial control platform were described in this paper. The model of the platform structure was established based on the dynamic principle. The platform stability between the frames and the effect of the mechanical error on the platform were studied. By incorporating the miniaturized strapdown/GPS integrated attitude measurement technology into the platform control technology, good platform stability and tracing efficiency have been achieved. The measured results are obtained as follows： 3 kg loading, pitch and roll variation between --15° ＋ 90°, azimuth between 0-360°, accuracy for horizontal attitude〈0.2°, accuracy for navigation〈0.3°.
