The angle of the elevator is controlled by a stick operated by the pilot. When the pilot
moves the control stick, it produces a control signal from the angular position sensor. This
signal is compared with the measured elevator angle by the controller and a control signal is
generated proportional to the error. The control signal is directly fed to the electro-hydraulic
servo valve which results in valve spool movement proportional to the control signal to adjust
the flow rate through the hydraulic cylinders. The pressure difference across the piston
provides the actuating force to rotate the elevato...
