드론의 비행 안정화를 위한 고도 보정 및 제어 알고리즘 개발
Recently, drones are widely used in many fields. However, as the size of the drone market has increased, accidents have been caused by various causes and the lives and property damage have been increasing. Difficulties in maintenance of altitude and falling, difficulty in locating drones, or sudden movements can lead to flying accidents, resulting in loss of life and property, and thus ensuring stable flight of drones. This paper has identified and improved the causes of altitude measurement error and motor speed fluctuation which are detrimental to the flight stability of drones. The altitude measurement error problem was solved by considering the flight characteristics of the drone, and the drone weight, manufacturing cost and calculation processing speed were reduced by using only the accelerometer. In addition, the problem of motor speed fluctuation due to battery voltage fluctuation can be easily applied to the flight control system and the motor without any restrictions by implementing it in the firmware. It can be seen that the stability of the drones is improved by improving the accuracy of altitude control during altitude control using altitude correction and control algorithms.
