Fuzzy theory application to the satellite antenna controller

In this paper, a satellite antenna controller bases on fuzzy theory is proposed. The high accuracy of satellite antenna controller plays an important role in the tracking system, but the dynamic characteristic of satellite antenna controller is nonlinear, and the noise in the external environment may affect the system. The fuzzy controller has high robustness, and there is no need for the well analysis to the mathematic model of the controller. Therefore, a fuzzy theory is employed to investigate the satellite antenna controller design herein. The antenna controller receives the feedback signals from resolvers and converts the feedback signals to point coordinates, antenna actual angles and rotation angles, and then displays the system information on a human machine interface. Finally, the experimental results proves the proposed satellite antenna controller with fuzzy theory is effective by performing the tracking of FORMOSAT-2 satellite.
