Abstract

The invention provides an airborne stabilization mechanism for an unmanned aerial vehicle. The airborne stabilization mechanism includes an upper platform, a lower platform, an actuator, a mechanism controller and joints; a mechanism controller fixed on the lower platform senses the attitude change of the unmanned aerial vehicle, based on this, the length of a push rod is changed by controlling the actuator which is fixedly connected through the lower platform through the three single-degree-of-freedom joints, an upper platform connected with the actuator through three double-degree-freedom joints is driven, the attitude change, in a space, of the upper platform just counteracts the attitude change of the unmanned aerial vehicle, a load fixedly connected with the upper platform can still keep spatial balance and stability when the unmanned aerial vehicle bumps and sways, thus the vibration intensity of the load of the upper platform is effectively reduced, and the spatial stability ofthe load is improved. The digital control mechatronic integrated stabilization mechanism based on the modern measurement and control principle has the obvious advantages of advanced technology and high precision and is suitable for various types of unmanned aerial vehicles and small aircrafts.

Description

technical field [0001] The invention belongs to the technical field of industrial automation control, and in particular relates to a high-performance, low-cost UAV airborne stabilization mechanism, which is suitable for the popularization and application of various types of UAVs and small aircraft, and avoids or reduces the turbulence of the UAV itself The effect of sloshing on loads attached to the platform. Background technique [0002] There are various mission loads of UAVs, and their effects are related to their own accuracy and the peripheral environment. Generally, mission loads have corresponding requirements for the flight characteristics of UAVs, especially requiring UAVs to maintain a certain attitude stability during flight. However, this puts forward strict requirements on the UAV body, which cannot be fully realized in many cases. [0003] The loads of existing small and medium-sized UAVs are mostly fixedly connected to the UAV. When the UAV is violently bumpe...
