Introduction and brief history
Introduction and Brief History

  • Pre 1947: First Autopilots controlled flight path and gave level flight. System comprised of spinning weightsthat maintain a specific orientation

  • 1947: The U.S. Air Force successfully tested the first fully functioning autopilot system. The system controlled takeoff, landing, and flight path.

    • These early systems were prone to error and required a full staff to work them

  • Now: “Fly by wire” systems are the most common. Computers do most the flying.


  • Functions
    Functions

    • Guidance

      • Measures the condition of the aircraft

      • Outer Loop

      • Does not actually guide the aircraft

      • Feeds the values into the control loop


    Functions1
    Functions

    • Control

      • Does the actual work

      • Receives values from guidance and controls the aircraft.

      • Two major controllers:

        • Longitudinal

        • Latitudinal





    Matlab
    MATLAB

    • Simulation Attempt
