线振动下惯导平台参数辨识的实现

 研究了软性连接条件下线振动试验辨识惯导平台陀螺参数的方法。由于在此条件下原始模型不便用于辨识参数，为此提出了平台漂移的平均模型。对比静态模型指出了线振动对模型参数辨识的实质作用。由于利用平均模型来辨识平台参数存在参数冗余的局限性，因此利用两组不同幅值的线振动试验数据来进行辨识。最后验证了这种辨识方案不仅避免了静态条件下高阶陀螺参数难以收敛的问题，同时也解决了平均模型中参数冗余的局限性问题。

Realization of Parameter Identification of Inertial Platform Under Linear Vibration

This article studies the parameter identification for gyros on inertial platforms with buffered connection under linear vibration. Since the original drift model of inertial platform is unsuitable for parameter identification under such conditions,an average model is presented,and a comparison between the average model and the static model demonstrates the essential influence of linear vibration on parameter identification. Meanwhile,since the limitation of parameter redundancy exists in the average model,a...
