MANY POINTS POSITIONING CONTROL OF A PNEUMATIC CYLINDER FOR A VERTICAL AXIS ACTUATOR USING TWO DEGREES OF FREEDOM PI CONTROLLER

抄録

Recently, pneumatic cylinders have become favorite actuators utilized as Z axis (vertical axis) actuators of indstrial robots and actuators for lifting or bringing down parts. Two degrees of freedom P1 controller is applied to the system in order to many points positioning control.
From some simulations and experiments, it is confirmed that the proposed control system is effective to improve the overshoot or undershoot and settling time for many points positioning [1], [2].
