数控机床速度伺服系统自适应控制研究

Adaptive Control for An 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 -0 1伺服系统进行仿真实验 。

For NC machine speed servo systems,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
