【 摘 要 】

Changing the dynamic motion parameters of pneumatic equipment requires control of pressure and the volumetric flow rate. The article presents a study of the impact of setting control parameters and external disturbances on the positioning accuracy of pneumatic rodless double acting actuator. Testing process was carried out at different values of the parameters (adjusted to the actuator) and external loads. The probe mass was selected within guidelines (a cushioning diagram) so that the operating point was placed on the curve of limiting movement speed of the actuator..
