摘要
空中移动通讯平台目前越来越多地应用于军事领域,由于在点对点信息无线传递过程中,通讯设备需要具有一定的方向性,最好是相互对准,从而增加信息通讯效率、减小误码率。基于飞艇的天线姿态控制系统由位置反馈、速度反馈和电流反馈组成三环数模混合控制系统,采用了稳定回路与跟踪回路相结合的姿态控制系统设计实现天线实时指向运动,架构了基于三坐标系的姿态解算数学模型,在较为恶劣的模拟环境下对系统进行了计算机仿真,结果表明系统满足预期设计指标要求,有效地隔离了飞艇运动对天线对准目标所带来的影响,响应速度快,对被控对象的非线性和时变性具有一定的自适应能力。
Air mobile communication platform serving for repeaters is more and more being applied in military fields. Antennas of communication instruments need aligning each other in wireless transmission process between two long 2 distance points, thus it Can make communication efficient and reduce error rate. Antenna＇s attitude control system based on aeroboat is a 3 - loop DA mixed control system composed of position feedback, velocity feedback and current feedback. The attitude control system combined with stabilized loop and tracking loop realizes real -time pointing movement of the antenna and builds mathematic model based on 3 - axis coordinate. The simulation in bad environments showed that the system can reach anticipated technical goal. It isolates the influence of aeroboat＇s movement effectively, responds quickly, and it has better self - adapting ability to non - linear and time -- changing of controlled object.
