Micro four-rotor aircraft based on F28335 control and control method

Abstract

A micro four-rotor aircraft based on F28335 control and a control method are provided. At present, the four-rotor technology in China is not very mature. In some complex environments and under the condition of external interference, the flight effect is not ideal. It is necessary to enhance the load-carrying flight capacity and on-load flight capacity of the four-rotor aircraft. The micro four-rotor aircraft based on F28335 control is composed of an onboard part (11) and a ground part (12). The onboard part is provided with a flight attitude acquisition and control module group (4) containinga F28335 main control chip. The F28335 main control chip is electrically connected with a power module (5), a wireless transceiver module (9) and a motor drive module (6). The motor drive module is electrically connected with the power module and a brushless motor (7). The technical scheme is applied to the micro four-rotor aircraft based on F28335 control and the control method.

Description

Technical field: [0001] The invention relates to a miniature four-rotor aircraft controlled based on F28335 and a control method. Background technique: [0002] The concept of quadrotor aircraft has been around for a long time. Its advantage is that its mechanical structure is relatively simple, and it can be controlled only by changing the speed of the four motors, and its flight maneuverability is more flexible; by expanding its functions, it can be used to carry out Image data shooting, survey of natural environment, detection of high buildings such as bridges and tall buildings, survey of terrain and geomorphology in harsh environments, detection and situation understanding of hazardous disaster relief environments; so study the flight attitude control of micro quadrotor aircraft in complex environments , not only can make it complete some difficult tasks, such as environmental monitoring and gas sampling, but also can be applied to actual production, such as disaster pr...

In some more complex environments (such as in the woods) and in the case of external interference (such as windy weather), the flight effect is not good. Not ideal; in addition, the load-carrying flight capability of the quadrotor needs to be enhanced so that it can maintain the original flight height and stable attitude with load
