Study for Dynamic Characteristics of Antenna Gimbal Stabilization System on the tracked vehicle

The present tactical environment is an environment in which a network is connected and operated. In order for the satellite communication terminals equipped with mobile devices to communicate with satellites in high quality and high capacity, it is essential that the stabilizing technology overcoming external disturbance is used. In the previous research, the motion equation for gimbal of the satellite communication terminal was presented. In various research, improvement of velocity and position control considering application of inertia, friction, unbalance moment, etc. Techniques for improving eye stabilization control performance with various feedback sensors and PI control have been introduced. Especially, it is necessary to consider the system dynamics and the control bandwidth to secure the stabilization technology according to the demand for weight reduction in the harsh environment of the military, and to secure the stabilization technology considering the influence of applied sensors and environmental disturbance. In this study, we analyze the influence of the dynamic characteristics of the optimized antenna gimbal shape and the control bandwidth, and we analyse the influence of the real external disturbance when connected to the tracked vehicle.
