摘要
单轴气浮台是卫星单通道全物理仿真实验的关键设备,其通常的姿态动力学控制研究,都是在假设其转轴是绝对垂直的条件下进行的,而实际上其转轴有一定的倾斜角并引起重力矩,对气浮台转动产生长周期作用从而影响到系统控制精度。因此,本文建立了相应的数学模型对其进行了动力学分析,并对这些重力作用进行了反馈补偿和设计了该气浮台的姿态控制系统。在此基础上进行了全物理仿真试验。
The key equipment of full physical simulation experimentation of single satellite channel was single axis air bearing table, and research on dynamics control of its attitude was done, when its shafts were assumed to be absolutely vertical. However, gravity moment was produced by a certain tilt angle between the shafts in fact, and it had a long cycle effect on rotation of single axis air bearing table so as to influence precision of system control. Therefore, the corresponding mathematical model was establi...
