摘要
针对位置随动控制系统具有不确定性的特点,设计了具有良好跟随性的自适应控制系统。利用机理法建立数控机床刀具进给定位控制系统的数学模型,将该系统等效为带有参变量的单输入单输出系统,在该模型的基础上设计了基于李雅普诺夫稳定性理论的模型参考自适应控制系统。利用Matlab进行仿真,其仿真结果表明,基于李雅普诺夫稳定性理论的模型参考自适应控制系统具有良好的跟随性、稳定性和控制精度。
A model reference adaptive control system witch of good following characteristics is designed for the uncertainty of the position servo system. The model of numerical control machine system is discussed with the uncer- tain system equivalent to the one with parametric variable single input and single output to establish a Lyapunov - MRAC （Model Reference Adaptive Control） system. The Matlab simulation results show that the Lyapunov MRAC system has good following characteristics, stability and precision.
