一种用于舰载无人机通信的天线伺服系统设计

Design of an Antenna Servo System for Ship-borne UAV Communications

为克服舰载设备使用稳定平台的可靠性问题,提出并设计了一种脱离稳定平台用于舰载无人机通信的天线伺服系统;该天线伺服系统用于舰艇对舰载无人机的实时跟踪,具有自动跟踪和手动跟踪两种工作模式,并且结构简单、工作稳定、响应速度快;从系统设计原理出发,阐述了系统的机电作动机构、角度跟踪算法、系统硬件电路设计以及伺服电机控制策略;实验表明,该伺服系统能够实时对舰载无人机进行精确跟踪,从而保障舰艇与无人机的有效通信。

In order to overcome the reliability problem of stabilized platform used for shipboard equipment, a kind of out of stabilized platform antenna servo system for the communication between ships and ship--borne UAV is put forward and designed. This antenna servo system, with two kinds of working mode： automatic tracking and manual, is used for vessels of ship--borne UAV real--time tracking. This paper also expounds the system of electromechanical actuation mechanism, tracking algorithm, the design of system hardware circuit and servo motor control system. Experiments show that the servo system can track of ship--borne UAV accurately, thus the effective communi- cation between ships and UAV can be ensured.
