【Abstract】 The principle and structure of the rotary cylinder position control system controlled by the proportional valve were discussed in the paper. Using "LabVIEW + PAC"as the control platform,the characteristics of the pneumatic proportional value were tested and the position control of the rotary cylinder was achieved with the controlled variables displayed in real-time. The experiment shows that the system runs well and data acquisition and process control can be completed efficiently and reliably.更多还原
