Four-rotor aircraft based on AVR single chip microcomputer

Abstract

The invention belongs to the technical field of aircrafts and discloses a four-rotor aircraft based on an AVR single chip microcomputer. The four-rotor aircraft based on the AVR single chip microcomputer comprises a main control module, a remote-control communication module, an inertia measurement module, a power supply module and a driving module. The four-rotor aircraft has the advantages of being simple in mechanical structure, low in cost, low in accident rate, light in weight and the like, the four-rotor aircraft with the functions of self-stabilizing, hovering, returning and the like ofthe aircraft can be realized, meanwhile, the four-rotor aircraft is controlled through cooperation with a double-closed-loop cascade PID control algorithm, and finally online debugging is carried outthrough an upper computer software, an outdoor on-site flight test proves that the four-rotor wings can stably take off well, actions such as self-stabilization and hovering can be completed, such that the purpose of the design is achieved.

Description

technical field [0001] The invention belongs to the technical field of aircraft, in particular to a four-rotor aircraft based on an AVR single-chip microcomputer. Background technique [0002] At present, the closest existing technology: the quadrotor aircraft is a multifunctional working system; It is recognized by all walks of life, so the utilization value of the quadrotor is very high. [0003] The origin of quadrotor aircraft can be traced back to the beginning of last century. However, due to the constraints of mechanical structure and control technology at that time, the development of quadrotor aircraft was quite slow. In recent years, with breakthroughs in micro-control technology, information technology, and sensor technology, quadrotor aircraft has entered a stage of rapid development. Many famous foreign universities and laboratories have developed different quadrotor aircraft and control algorithms. For example, the miniature quadrotor aircraft developed by Vi...

[0003] The origin of quadrotor aircraft can be traced back to the beginning of last century. However, due to the constraints of mechanical structure and control technology at that time, the development of quadrotor aircraft was quite slow.

Domestic research on quadrotor aircraft is in the ascendant stage, and there is still a long way to go compared with foreign countries, but our country has achieved many good results on aircraft, whether it is in the control algorithm of quadrotor aircraft or in Remarkable results have been achieved in practical applications. At present, the State Grid Power Supply Company uses unmanned aerial vehicles equipped with lidar to carry out inspections of transmission lines in many provinces; The influence of components, resulting in poor flight attitude

During the flight of the quadrotor aircraft in the air, it will be interfered by the wind direction and electromagnetic field, and the design defects of the quadrotor itself. These disturbances will cause the signal collected by the sensor to contain a large number of harmonics, which will affect the flight of the quadrotor.
