Multiple Channel High Accuracy Position Control for Servo Hydraulic Control System

Hardware/Software  – CRIO, LabVIEW, LabVIEW RT & FPGA

Description – LabVIEW user interface on Microsoft Windows PC for setup and visualisation, communication via ethernet to 3 cRIO controllers providing high accuracy servo control. The architecture of the control system used 3 cRIO controllers with a computer system providing the user interface. Each cRIO controller and computer system is connected to a local network providing the communication backbone for the system. Synchronisation of the controllers is provided so each actuator moves to the desired position at the right time. As this is critical to forming the part correctly a digital clock signal is transmitted by the system master cRIO controller to each cRIO system. The profile of movement to be achieved by each axis is downloaded to the each cRIO controller which then generates the required set-points for each control loop. Generating the data stream for each control loop is performed on the realtime platform therefore minimising the network traffic while providing smooth axis movement.
