摘　　要：针对电液混合式注塑机提出了一套伺服控制机构和相应的控制策略,并对整个系统进行了MATLAB仿真和试验验证。该控制系统选用交流永磁同步电动机,采用id=0的矢量控制模式,对压力和流量采用模糊控制策略。结果表明:id=0矢量控制的永磁同步电动机伺服系统具有良好的伺服性能;模糊控制策略能够实现整个系统的保压压力稳定跟随设定压力曲线。A set of servo control mechanism and the corresponding control strategy for the electro-hydraulic hybrid type injection molding machine was put forward,and the system was simulated and tested by MATLAB.The control system of AC permanent magnet synchronous motor,which used id =0 vector as control mode,and the the fuzzy control strategy was used for pressure and flow.The results show that the id =0 vector control servo system has good servo performance.The model system of the holding pressure can follow set of stable pressure curve,and fuzzy controller has good control effect.
