Abstract:
This article presents a study of mathematical models of double acting pneumatic cylinders by
the study and comparison research of the past. Every single article has different variables , it based on
the conduction of mathematical equation used in controlling certain type of variables, such as positioning
movement control, cylinder pressing control or piston speed control. The important variables in controlling
are not equal and the precision of control is another factor in determining the number of variables. The
study found that the mathematical principle of double acting pneumatic cylinder has equal number of variables
that contain of three sections, first is the rate of air flow in and out which consists of sectional area
of the air (A) and pressure (P), the rest of the gas is constant. Second is the equation collected of energy
in the air chamber that contains volume embraced of air chamber (V) and the flow rate of air (G). Double
acting pneumatic cylinder consists of 2 air chambers so that, the two air chambers are connected by the
equation of section 3 which is the equation of piston motion with the difference of the energy collection
that causes cylinders air force and motion.
