Abstract: A description is given to the importance and designing demand for the limiter of angle of attack and normal acceleration(AOA limiter )as well as some design methods utilized in foreign aircraft and domestic aircraft . The advantages and disadvantages of these methods are analyzed, and some work is done in logic feedback limiter′s design method.A method is introduced to calculate the parameters in the limiter. It is a useful way to ensure normal design of boundary limiters.

Key words: angle of attack, cont rol, acceleration (physics)
