Control and positioning of a pneumatic cylinder

This thesis work is based on the control and positioning of pneumatic and oil-pneumatic cylinders. These actuators are chosen since their high power-to-weight ratio. Also, they presents more advantage as a low cost maintenance. The entire panel is designed in order to optimize the overall dimension of the means that are used. In particular, fixed devices are PLC , HMI and two cylinders: pneumatic cylinder and oil-pneumatic cylinder. Meanwhile, there are two pneumatic configurations: four electro-pneumatic 2/2 NC valves and two 3/2 NC valves. The goal of this work is using different controls in order to manage the cylinders position, as shown in the following chapters. At the end of each section, a comparison between different control technologies are made, in order to obtain better work conditions and response parameters for each experiments. Also, in the final chapter, is reported a global comparison in order to highlight the best strategy control.
