针对依靠空气动力机动飞行的飞行器飞行轨迹受平稳风场影响大的特性,提出了一种以过载控制辅助实现风速辨识的方法。对地面风场特性进行了分析,建立了简化的风场模型,利用铅垂方向风场分量近似为0的特性推导了风场辨识算法,然后阐述了风速辨识流程,给出过载控制实现方案、风场估算公式,最后通过数学仿真验证了该方案在线辨识风速的有效性,为实现制导控制系统实时弹道风修正提供了技术支撑。
Aimed at the fact that the flying trajectory of aerodynamic maneuvering aircraft is greatly affected by the steady wind field, a method of identifying the wind speed with the aid of overload control is proposed. Based on the analysis of wind field characteristics and the simplified model of wind farm, a wind field identification algorithm is deduced by using the characteristic that the component of vertical wind field is approximately 0, then the flow identification process is described, and the realization scheme of overload control is given. Finally, the effectiveness of the scheme for on-line identification of wind speed is verified through mathematical simulation, which provides technical support for the real-time trajectory correction of guidance and control system.
