摘　　要：压力和流量是注塑机控制系统中2个极为重要的控制量,其控制性能和控制精度将直接影响注塑成型的质量,目前广泛采用的控制方法存在动态响应性能差和控制精度低的问题,针对注塑机生产工艺要求,对注塑机伺服驱动系统的压力控制和流量控制模型进行深入研究,在此基础上提出了一种新型基于压力偏差切换调节器参数的压力环限流量控制算法。最后将该方法应用于注塑机系统当中,经过实际测试证明该算法可以有效提高注塑机系统的动态响应性能和控制精度,获得更好的控制效果。The pressure and flow are two important parameters in the control system of injection moldingmachine,weigh heavily on the quality of the injection molding. To solve the problem of poor dynamic response and lowprecision,analyzed the mathematical model of pressure and flow control of servo motor drive system,also meets thecommon pursuit of injection molding machine,the composite control strategy through the method of pressure controlwith flow limit was put forward. Eventually,applied the method of the injection molding machine system,after stricttest and practical,the above advanced control method meets with the high-precision and high response requirements ofthe injection system,gets better control effect.
