Robust adaptive control of UAV

Aiming at the problems of UAV dynamic modeling error and flight interference, robust control algorithm is introduced in this paper. Based on the establishment of UAV motion equation, the state equation of robust control is obtained by linearization, then the weight function is selected and the controller is designed. MATLAB simulation results show that Compared with PI control, robust longitudinal control of UAV has the characteristics of fast response, small overshoot, short adjustment time and insensitive to modeling error, which shows good control performance.
