Abstract

A model of an azimuth driving servo system with a flexible antenna in a tracking system was derived in this work. The validity of the model was verified by comparing the results of the model with experimental results. When modeling the dynamics of a gimbal with an antenna, the antenna should be considered as a flexible body. The effect of reducing the magnitude of the backlash that results in extending the bandwidth in a system with a flexible antenna is smaller than the effect of reducing the magnitude of the backlash in a system with a stiff antenna. When there is a need to reduce the weight and extend the bandwidth, the derived model enables the design of a tracking system to be optimized
