摘要
研究了存在安装误差时基于加速度计比力信号解算高自旋弹丸角速度和姿态角的方法。设计了一种十二加速度计配置方案,建立了存在安装误差时的角速度解算数学模型,采用非线性最小二乘法的阻尼高斯牛顿法研究了算法精度。结果表明该方法能有效抑制安装误差,精度高,具有工程应用价值。
A method of solving the angular speed and attitude angular of high spinning projectile was proposed by accelerometers' specific force signal in existence of installation errors.A twelve-accelerometer configuration was designed,the mathematical model of solving angular speed was established in existence of the installation errors,the algorithm precision was researched by the damping Gauss-Newton method of nonlinear least squares.The simulated result indicates that the method can suppress installation errors effectively,has high precision and engineering application value.
