摘要
针对大型数控机床中由于导轨及执行元件存在摩擦转矩而引起的低速抖动问题，提出一种变ＰＩＤ参数的混合模型参考自适应控制算法．本算法对机床低速爬行具有很好的克服效果系统的仿真实验表明：本算法具有定位精度高、系统快速性好。
This paper mainly discusses the slow speed vibration problem caused by dry friction of large scale Numerical Control machine tool,and suggests reference adaptive control.Scheme of mixed model changing PID parmeter.This algorithm has better Robustness to the solw speed creep of machine tool.The system simulation tests show:this algorithm possesses the properties of high positioning accuracy,rapidity and stable slow speed track.
