Abstract
This paper introduces a kind of control servo system and its corresponding control strategy for the electro-hydraulic injection molding machine. A MATLAB simulating research was conducted on the system in which AC Permanent Magnet Synchronous Motor (PMSM) was used, vector control mode of i d = 0 was applied, and fuzzy strategy was adopted for controlling pressure and flow. One conclusion we draw from the results was that servo system driven by PMSM and with vector control mode of i d = 0 had good performance. Another conclusion was that fuzzy strategy was useful in controlling the pressure of the system and could allow the pressure to change according to the established pressure curve.
