| 摘 要： | 针对弹载捷联式天线平台的视线稳定问题，提出了补偿与反馈控制相结合的方法。通过分析，给出了捷联式稳定的数字实现方法，并考虑实际系统中陀螺非线性、测量噪声和加速度敏感度等因素的影响，对平台稳定性能进行了仿真研究。结果表明：该方法能够使弹体扰动造成的误差明显减小，在一定的测量噪声和加速度敏感度范围内，算法能有效隔离弹体扰动。

| Abstract: | The technique of feedforward compensation combined with feedback control was put forward and applied to stabilize Line-of-Sight (LOS) of strapdown antenna platform. The scheme for digital realization was presented by analysis. Simulation of platform with gyro nonlinear factor, measuring noise and sensitivity to acceleration was carried out for availability checkout. The results show that compensation can reduce error. The method is proven to be effective in reducing body disturbance within the scope of definite gyro noise and sensitivity to acceleration. |
