以三轴转台作为测试设备,提出了用双轴位置滚转法和双轴速率滚转法对捷联惯性组合进行测试,同时应用D-最优设计准则对试验计划进行了设计,给出了一个在三轴转台上实施的优化测试方案。该方案可以辨识出捷联惯性组合角速度测量和线加速度测量模型方程中除角加速度误差系数外的全部系数。
Taking the three-axis turntable as the test equipment, the strap-down Inertial combination test is proposed by using the biaxial position rolling method and the biaxial roll rate method. At the same time, the experimental design is designed with the D-optimal design criterion given An optimized test solution on a triaxial turret. The scheme can identify all the coefficients except the angular acceleration error coefficient in the strapdown inertial combined angular velocity measurement and linear acceleration measurement model equations.
