Modern aircrafts design is tending to employ automatic control in their every part.In this paper, an autopilot is designed to control the pitch of an aircraft using both PD-like type-1 and type-2 fuzzy logic controllers. The flight system is exposed to atmospheric effects like wind speed, rain, temperature… etc, and noise from the system,which affects the response. To test the effectiveness of the two controllers, three different cases are simulated; system without disturbance and system with slow and fast varying disturbances.
