Satellite antenna pointing complex controlling full-physical simulation system error model and its examination analysis

To improve the precision of the satellite antenna pointing full-physical simulation, in this paper, on the viewpoint of mechanics, several unideal factors that affected the antenna pointing complex controlling precision were researched when the Satellite Antenna Pointing Complex Controlling Full-Physical Simulation System was tested. And the system error was analyzed and studied. The error model was given too. Then the adaptive controlling law had been designed and its stability had been proved. In the end, the simulation results were given. The simulation results have shown that this system can satisfy the high-precision requirement of Satellite Antenna Pointing Complex Controlling. This work establishes the base of the further improving satellite antenna pointing complex controlling precision.
