Study of optimization method for flight path following

Minimizing the tracking deviation between the real path and the referenced path can produce optimal following path, but it will bring a considerable oscillation of optimal control variables. In order to alleviate the considerable oscillation, an integrated control method that combines the deviation with its differential was presented. The numerical application of the integrated control method demonstrates that the proposed method is effective and valid with respect to the possible oscillation of optimal control variables. Consequently, the precision performance of the flight path following is further realized.
