摘　　要：根据多项式回归理论,用数学语言描述注塑机的电机传动系统过渡惯性对V/P切换位置控制的影响,并构建了二者的拟合曲线函数,能够预测任意速度下V/P切换位置的控制误差,预测结果可以对注塑机设定值进行补偿,提高注塑机V/P切换位置控制的稳定性。According to the polynomial regression theory,the influence on V/P switching position control of transition inertia of motor drive system of injection molding machine was described in mathematical language,the fitting curve function of the two parameters was constructed,which could predict the control error of V/P switching position at any speed,and the prediction results could compensate the set value of injection molding machine and improve the stability of V/P switching control of injection molding machine.

关 键 词：注射工艺优化 过渡惯性 V/P切换 工艺波动 控制精度
