数控机床速度伺服系统自适应控制研究

Adaptive Control for NC Machine Speed Servo System

针对数控机床速度伺服系统,讨论一种具有鲁棒稳定性的模型参考自适应控制方法,提出一种简便的高阶状态变量获取方法以及一种鲁棒自适应算法,以便能消除由于有界扰动而引起的参数漂移。并对SCS—01伺服系统进行仿真实验,得到很好效果。

For NC machine speed servo system.a model reference adaptive control method with Robust stability is discussed and a simple high order state variable acquisition method and a Robust adaptive algorithm are proposed so as to eliminate the parameter shift caused by disturbances.The simulation for SCS-1 servo system shows good results.
