Study On The Adaptive Balance Control Strategy Of The Four-rotor Aircraft

With the development of science and technology,computers have gradually replaced labor in many aspects.The four-axis aircraft has received wide attention from technologists and has been widely used in various fields.Based on the development of quad-axis aircraft,a self-adaptive stable control method is proposed and an adaptive stabilization controller is designed.The mathematical model of the aircraft was established to analyze the flight attitude of the four-axis aircraft,at the same time the Kalman filter and the vector transformation method are combined to obtain the desired effect.The method and flight control system of data fusion algorithm are studied in this paper.In the control of aircraft,the stability control of the aircraft is eliminated by filtering the acquisition signal.The attitude control system is simplified to a second order system,which is realized by PD algorithm.Based on the system,a conventional PID controller is used to control the height of the aircraft.The parameters of the four-axis aircraft are modified by the test flight,so that the PID control can realize the adaptive and stable control of the aircraft,then we finish the hardware building and experimental testing.The experimental results show that the filter has a good effect on the mechanical vibration,and PID regulation control plays an important role to keep the balance of the aircraft running under the external environment interference.
