摘要
设计了一套用于小卫星姿态控制全物理仿真的新型实验系统;该系统基于滑台式气浮台,采用回转中心与质心重合方法解决了气浮台力矩平衡难题;设计了独立的供气和供电系统,对供气、供电、星载计算机、执行机构和敏感器等分系统进行了设计,满足卫星控制全物理仿真要求,采用CAN总线技术和串口技术实现了星上部件之间以及地面站对其遥测遥控的通讯,并以双边极限环控制法为例,进行了卫星姿态控制全物理仿真实验,结果证明了该系统仿真结果精确,在小卫星仿真测试中具有实用价值。
A new kind of full-physical simulation experiment system of moonlet attitude control is introduced. The system based on air bearing test-bed solve the moment matching problem by making circumvolve center and mass center superposition. The system has independent air supply subsystem and electricity-supply subsystem. The satellite computer communicates with the remote control subsystem by the CAN bus technology and the Serial Port technology. The design of the air-supply subsystem, electricity-supply subsystem, satellite computer, the actuators and the sensors settles for the full-physical simulation. Also, the two sided limit cycles control method is sim ulated by the system, and the result of test proves the utility and accuracy of the system.
