This paper investigates the design of the flight control system of multi-purpose drones with the transition flight mode in the longitudinal motion and analyzes the system through the simulation. The dynamic characteristic of the multi-purpose drone is mode dependent. Thus, the flight mode is separated into hover flight, transition flight, and level flight. Each flight mode has a different flight dynamic model and a controller. The PID controller is used to design the controller, and the stability analysis is done using the typical root locus method. Then, the control system design is validated via a longitudinal-mode flight simulation with transition sequence logics.
