Research of Plastic Material Dynamic High-Speed Tensile Machine’s Measurement and Control System Based on FPGA

Abstract:

This paper will give a solution of measurement and control system based on FPGA embedded system for the Plastic Material Dynamic High-speed Tensile Machine (PMDHTM) with 1-100s^-1 strain rate range. Using sub-modules design of Nios II soft-wore and SOPC to build measurement and control system. The state machine algorithm and servo drive device are applied to accomplish precise state control of the linear shaft motor. Collecting the stress data online and non-contacting strain measurement is adopted. The test result can well meet the linear motor control response demand below the 5Hz frequency. Compared with other control based on SCM, DSP and so on, it supplies an innovation way for the PMDHTM control.
