Abstract: In this paper, the path tracking problems of single aircraft, towed system without drawbar, and towed system with drawbar were studied. Firstly, the path tracking problems of the three systems were transformed into optimal control problems, and acontinuous nonlinear path tracking model was established. Then, based on the third generation function, afull state symplectic pseudospectral method with a wider range of applicability was proposed. Combined with the theory of Receding Horizon Control(RHC), an online tracking optimal control method was proposed, and the proposed method was proved to be a symplectic preserving algorithm. Based on the proposed online tracking algorithm, the path tracking problem of the single aircraft, towed system without drawbar, and towed system with drawbar in the presence of initial deviations and continuous disturbances of were studied respectively. Compared with the BackwardSweep method, the results show that the proposed tracking method can effectively solve the tracking problem with control constraints and state constraints, and it's of higher tracking accuracy and computation efficiency, fully meeting the requirements of real-time tracking. Finally, the tracking characteristics of these three different modes were studied from the perspective of initial deviation and continuous external disturbance.
