摘　　要：为克服传统数控机床工作台伺服系统存在响应慢、动态性差等缺点,在常规PID控制的基础上应用模糊控制方法改进数控机床工作台伺服系统,使得伺服系统始终保持在最优的工作状态下,建立了数控机床工作台伺服系统的数学模型,以AMESim/Simulink软件为平台进行仿真,仿真结果表明:改进后的系统有更好的动态性、稳态性、鲁棒性以及控制精度.The traditional CNC worktable has the poor response and dynamic quality. This paper improved the quality by using fuzzy control method on the basis of the traditional PID control in order to keep the servo system at the best working condition all the time. This study first established the mathematical model and then ran a computer simulation on the software of AMESirrdSimulink. The simulation demonstrates that the improved system has a better robustness quality control precision.
