摘要

本文推导了一种带有柔性天线的跟踪系统的方位驱动伺服系统模型。通过与实验结果的比较，验证了模型的有效性。在对带天线的万向节进行动力学建模时，应将天线视为一个柔性体。在使用柔性天线的系统中，减小导致带宽延长的间隙幅度的影响小于使用刚性天线的系统中减小间隙幅度的影响。当需要减轻重量和扩展带宽时，推导出的模型可以优化跟踪系统的设计。

Modeling on a Gimbal with an Antenna and Investigation on the Influence of Backlash

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 e ﬀ ect of reducing the magnitude of the backlash that results in extending the bandwidth in a system with a ﬂexible antenna is smaller than the e ﬀ ect of reducing the magnitude of the backlash in a system with a sti ﬀ 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.
