Problems solved by technology

General unmanned aerial vehicles need to use electricity (battery), thermal energy (hot air balloon) or solar energy for energy supply, so this conventional method has the following disadvantages: first, energy supply is difficult, consumption is fast, and the aircraft cannot maintain long-term navigation; Second, the conditions are harsh and require sufficient sunlight (solar energy) or sunny weather (hot air balloons); third, the cost is expensive and the maintenance price is high
However, the current control of such aircraft is often based on human control, which cannot be applied to long-term automatic monitoring, nor can it meet the needs of automation, intelligence, accuracy and reliability.

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 Shown, the fuzzy control method of air long-endurance floating platform of the present invention, its steps are:

[0028] (1) Build a traction control platform; such as figure 2 , image 3 , Figure 4 , Figure 5 As shown, A in the figure is the traction rope, and B is the aircraft. The traction control platform includes a turntable 1, a pitching motion platform 2, and a motion platform 3. The pitching motion table 2 is installed on the turntable 1 and rotates with the turntable 1. The motion platform 3 is installed on the pitching motion table 2 and moves along with the pitching motion table 2. The motion platform 3 is provided with a wire wheel 4 , a code disc 5 , a first roller 6 , a pressure sensor 7 , a second roller 8 , a two-dimensional force sensor 9 and a traction drive assembly for driving the w...

Abstract

The invention discloses a fuzzy control method of a floating platform in aerial long flight. The fuzzy control method comprises the following steps of: (1), construction of a traction control platform which comprises a turning stage, a pitching movement stage and a movement platform, wherein the movement platform is provided with a rope winding / releasing mechanism; (2), horizontal pitching control of a traction rope: PID control is adopted to realize horizontal and pitching tracking control of the traction rope, and input is output of forces at horizontal and pitching directions of the traction rope, wherein the forces are measured by a two-dimensional force sensor, and control signals of the turning stage and the pitching movement stage control a horizontal angle beta and a pitching angle alpha of the movement platform, such that the horizontal and pitching forces of the traction rope which are measured by the two-dimensional force sensor are zero, and therefore, horizontal deviation delta beta and pitching deviation delta alpha can be zero; and (3), and winding / releasing control of the traction rope: fuzzy control is adopted to realize the winding / releasing control. The fuzzy control method of the floating platform in aerial long flight of invention has the advantages of simple principle, convenient control, operational easiness, high control precision and the like.

Description

technical field [0001] The invention mainly relates to the field of monitoring equipment, in particular to a control method suitable for a long-endurance floating platform in the air. Background technique [0002] At present, some practitioners have proposed many types of high-altitude monitoring systems, which mainly use a large number of cameras to monitor and shoot large-scale fixed-points on the ground, aiming at low- and medium-altitude reconnaissance, network coverage, forest fire prevention, commercial entertainment and other military and civilian fields. This type of high-altitude monitoring equipment is generally located in fixed buildings, trees or other high fixed positions, but due to the location of the camera installation, once this type of monitoring equipment is installed, its monitoring range is very limited. [0003] For mobile shooting at low and medium altitudes, the currently commonly used solution is to use unmanned aerial vehicles to perform related ta...
