Design of Stabilized Platform Controller for Mobile Satellite Communication System

Abstract:

The stabilized platform servo system ensures the carrier communicating with satellites stably while in motion. The key to this system is to isolate disturbance coursed by the moving of the carrier and maintain the stability of antenna directivity. This paper has compared PID algorithm and I-PD algorithm, and designed a control scheme for the stabilized platform using the combination of speed-change integral I-PD algorithm and feed-forward control. The results of the simulation and actual testing indicate that the design this paper presents has a strong suppression to disturbance and meets the precision requirements of the mobile satellite communication system.
