Due to the high requirements of lateral-directional control accuracy and flight quality for some unpowered vehicle during approach and landing phase, and its severe lateral-directional coupling, the traditional PID control method fails to ensure flight quality that satisfies design requirement. In view of the above problems, this paper proposes a roll attitude optimal control method. By using traditional PID control method and optimal control method independently, six-degree simulation is conducted. The simulation task is making roll angle track step signal command. Simulation results show that optimal control method can realize stable roll attitude control effect under various deviations, and the response curves of roll angle and sideslip angle are smoother compared with the PID control method, there is no overshoot and no shock by using optimal control method, and the optimal control method can achieve satisfactory flight quality. As the optimal control method has simple control structure, it is easy to realize in engineering practice.
