In this paper, we have studied on the flight path generation using polynomial and the flight path tracking control using guidance law, speed hold system, ACAH (Attitude Command Attitude Hold) system. The modeling section of the flight path is divided into five regions, and each region is modeled by a 7SUPth/SUP order polynomial. The flight paths were defined as maneuver library. MTEs (Mission Task Elements) of aeronautical design standard (ADS)-33 have been used to construct the Maneuver library. The Line-of-Sight(LOS) method and classical control method were applied to design the guidance law, speed hold system, and ACAH system for tracking the flight path. Simulation was performed to show that it is possible to generate mission flight path by combining the maneuver libraries. Also, it is shown that the trajectory tracking control is possible. Therefore, since the results of this study enable the real-time trajectory generation and the tracking control, it will be useful to improve the probability of mission success and survivability of UAV (Unmanned Aerial Vehicle).
