Abstract(in English) | We have studied a high precision outo-tracking antenna system. The antenna system consists of a 2-axis stable platform, a 2-axis antenna driving mechanism and an antenna reflector that is fixed on the antenna pointing mechanism. Controller has two functions. They are a stable platform controller and an antenna-pointing controller. The stable platform controller is designed using a H-infinity control method, which takes into account characteristics of sensors drift, vessel's motion and other disturbances derectly in frequency demain. And a dithering method is adopted for the antenna pointing mechanism. Simulation results show that the proposed antenna system realizes the high pointing accuracy and cost-effectiveness. |
