| Abstract: | To implement a simulation of air-floating-platform with higher frequency vibration, A satellite-gesture emulation system with the functions of selectable high-frequency vibration-simulation and high-accuracy stability (with the control resolution within ±5×10-4 angle-degrees), controlled by using filtered-feedback and fuzzy-preeminence technology is designed and structured. The system is based on the analysis of dynamic and static composed-force-moment and disturbance factors. Through computational simulation, laboratory experiments and field-demo, it is proved that the system operation is available, practical, and propitious for minifying drive-power. These system structures and control strategies can be widely used in the fields such as astronomy, space navigation, deep-sea operation, high altitude motion, and weightless experiment, where a floating body must be controlled or simulated. |
