摘　　要：在数控机床的进给伺服控制系统中，采用带前馈的数字ＰＩＤ调节器与伺服放大器构成前馈反馈复合控制，并采用变结构控制，可显著提高数控系统的控制精度，特别是能够大大降低轮廓加工时的跟随误差。实验结果表明，这是一种有效和切实可行的控制方法。The control accuracy for numerically controlled machine tools can be improved greatly by using compound control with feedforward feedback control and variable structure control in a feeding servo system Specially,the following error in outline machining can be reduced substantially The experimental results shown that the compound control is available for the feeding servo system
