gravity disturbance meaning in Chinese
重力扰动
重力异常
Examples
- Because it is impossible to adjust the air bearing absolutely balance , the difference between mass center and rotation center must lead to a notable gravity disturbance torque . in the process of identification , modeling and identification of gravity disturbance torque is considered , and an extended kalman filter is educed for identifying air bearing inertia matrix and gravity disturbance torque , and then the algorithm is validated
由于气浮台平衡调试方法和手段的限制,实验过程中气浮台质心与转动中心有一定的位置偏差,必将导致较大的重力干扰力矩,在辨识算法的推导过程中,重点考虑了重力干扰力矩的建模和参数辨识问题,推导了气浮台的转动惯量和重力干扰力矩辨识的扩展卡尔曼滤波算法,并对算法进行了数学仿真和全物理仿真验证。 - The air bearing is the most important part of an attitude control system simulator for simulating a satellite moving in the weightless circumstance . performance of a satellite attitude simulation system based on air bearing is decided by the inertia matrix and gravity disturbance torque arising from a difference between mass center and rotation center , and air bearing can be used to simulate the algorithm of on - line mass - property parameters identification on the ground . so the problem of mass - property and gravity disturbance torque identification for satellite and air bearing is studied in this thesis
气浮台能够模拟卫星在轨失重条件下的姿态运动,是卫星姿态控制系统物理仿真的核心部件,其转动惯量和质心偏移引起的重力干扰力矩等决定了基于气浮台的卫星姿态物理仿真系统的性能,并且利用气浮台可以实现卫星质量特性在线辨识算法的地面物理仿真验证,因此本文对卫星和气浮台的质量特性及干扰力矩在线辨识问题进行深入研究。
