In order to solve the problem that the actual heading of the UAV in the initial stage of target tracking is inconsistent with the expected direction provided by the guidance vector field,a method of heading error correction based on dynamic inversion is proposed.Firstly,on the basis of UAV kinematics model,Lyapunov vector field guidance method is used to provide the tracking guidance law for UAV in target tracking.Secondly,by constructing the dynamic inverse structure system of UAV heading error correction, the heading error is gradually corrected in the initial stage of UAV flight,and the convergence speed of heading error is controlled.Finally,the initial heading of UAV is classified according to its region,and convergence of heading feedback is proved.The convergence speed and flight path of UAV initial course under different control parameters are simulated and verified,and comparison analysis is made with the arc compensation method.The simulation results show that the dynamic inverse correction method is effective and practical.
