Modeling and Control of Testing Device For Carpet Resilience Measurement*

A multifunctional testing device is designed to perform thickness measurement of carpets. Thickness loss is determined for two cases: after short-term static loading and after long-term static loading. Compression and resilience tests and measurements are performed simultaneously on five samples automatically using this testing device. Carpet thickness is measured after different loading conditions. This paper introduces the pneumatic proportional position control system utilized in a testing device. Actuation of the system is performed by using pneumatic actuators. The model is taken as a double acting pneumatic cylinder. PLC used for system automation and control. This testing device has been completed as a result of a research project. A mathematical model is also offered for the actuation system.
