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-1strain 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.

Mechanical properties of MEMS materials is one of MEMS important basic theory research, including hardness, elastic modulus, yield strength, tensile strength, fatigue strength and other performance indicators. For the acquisition and processing of weak signal can meet the system, this paper designs a measurement and control system which has a common set of software and hardware of high speed, high accuracy, high reliability in one. This tester is mainly composed of four parts: precision positioning subsystem, specimen clamping subsystem, load/displacement measurement subsystem and measuring and controlling subsystem, which provides a solid foundation in higher positioning accuracy of measuring MEMS materials and benefits more for further research.
