Four Fold-Frequency Subdivision and Direction-Judgment Control Unit Design of SMC CE1 Cylinder Based on FPGA

Abstract:

In order to improve the displacement output signal resolution of SMC CE1 series digital cylinders, a four fold-frequency subdivision and direction-judgment control unit based on FPGA is designed. The performance of the four fold-frequency subdivision and direction-judgment control unit is studied by simulation. The research results show that the four fold-frequency subdivision and direction-judgment control unit can improve the SMC CE1 cylinder displacement output signal resolution from 0.1mm to 0.025mm, which proves the validity of the four fold-frequency subdivision and direction-judgment control unit. This four fold-frequency subdivision and direction-judgment control unit can be used in the pneumatic closed loop control system of SMC CE1 series digital cylinder and greatly improve the system control precision. And this kind of four fold-frequency subdivision and direction-judgment control unit is also valuable for the resolution improvement of other SMC cylinders displacement output signals.
