摘要
中小型无人机应用广泛,但飞行过程中易受高压线电磁泄漏、广播电台、雷达站甚至人为无线电波干扰的影响,传统的导航与控制系统存在极大的安全隐患。本文阐述了强干扰环境下不依赖卫星的仿生自主导航技术的发展现状和最新进展;针对无人机导航与控制系统存在的多源干扰影响,论述了多传感器系统抗干扰滤波的必要性及应用条件;从内部组成、功能参数与应用等方面论述了国内外具有代表性的中小型无人机用抗干扰自动驾驶仪。指出仿生导航技术与抗干扰滤波技术是实现强干扰环境下的中小型无人机安全、可靠飞行的重要保障。
Small UAV is widely used in many fields. But it is susceptible to be disturbedby high-voltage electromagnetic leakage, radio stations, radar stations, and even effects of man-made radio interference during the flight. There is great danger in traditional navigation and control system. This paper describes the current status and the latest progress of bionic autonomous navigation technology which does not rely on satellite under strong interference environment. On account of multi-source interference in UAV navigation and control system, this paper also discusses the necessity and its application conditions of anti-disturbance filtering for multi-sensor system. Meanwhile, this paper introduces the most representative autopilots around the world which is used for small UAV, and discusses their composition, function and application. Finally, this paper states that bionic navigation and anti-disturbance filtering techniques are of importance for flight safety and reliability flight in strong disturbance environment of small UAV.
