摘要:

针对敌我识别(identification friend or foe,IFF)系统询问天线受舰船横摇、纵摇和航向姿态扰动,对空中运动目标位置跟踪不准确影响天线收发信号质量的问题,提出并设计了一种基于运动旋量目标位置解算的带前馈补偿的双电机联动PID控制方法。该方法基于雷达发送的空中目标方位、距离和俯仰角计算出目标坐标位置,然后将横摇、纵摇和航向3种干扰信号通过运动旋量变换嵌入目标位置并将嵌入后位置的方位角和俯仰角作为控制指令,将控制指令导数作为前馈补偿用于提高系统响应速度。仿真结果表明,该方法能够有效抵抗舰船3种姿态扰动并快速准确地跟踪空中目标。

Abstract:

In response to the issues of inaccurate tracking of aerial moving targets and signal quality degradation caused by pitch, roll, and heading disturbances affecting the interrogator antenna of the identification friend or foe (IFF) system, this paper proposes and designs a dual-motor coordinated PID control method with feedforward compensation based on motion twist for target position calculation. The method calculates the target’s coordinates using azimuth, distance, and elevation angle data provided by the radar. Pitch, roll, and heading disturbance signals are embedded into the target position through motion twist transformation, with the resulting azimuth and elevation angles serving as control commands. The derivative of these commands is used as feedforward compensation to enhance system response speed. Simulation results demonstrate that this approach effectively mitigates the three types of ship attitude disturbances and enables rapid and precise tracking of aerial targets.
