Problems solved by technology

Although there are some relatively complete and mature aircraft control boards on the market, most of them are multi-rotor quadcopters for aviation model enthusiasts. Most of them use low-cost and low-precision sensors, which are difficult to achieve the professional inertial guidance unit. Accuracy and reliability, so it cannot meet the actual requirements in terms of anti-external force disturbance, controllability, etc.
At the same time, these products often do not have or only have a very simple navigation method, and can only use manual remote control to control the flight within the visual range of the naked eye. The potential commercial value and practical value are far from being developed.

Description

technical field [0001] The invention belongs to the technical field of signal detection, and relates to an automatic navigation control system for a four-axis aircraft used for a cross-flow fan. Background technique [0002] Cross-flow fan, also known as cross-flow fan, is a special type of fan. The impeller is multi-leaf, long cylindrical, with forward multi-wing blades. It has simple structure, small size, stable air flow, and high dynamic pressure coefficient. Features, recently widely used in household appliances and air-conditioning equipment and other low-pressure ventilation occasions. Compared with the rotor as the driving method, the cross-flow fan has many advantages: since the axial length is not limited, the length of the impeller can be arbitrarily selected according to different use needs, and the power can be adjusted; the air flow flows through the impeller and is affected by the two forces of the blades , so it can reach a longer distance; there is no turbu...
