摘　　要：静压气浮溜板主要用在超精密加工机床中,它的振动将通过刀架直接反映到被加工工件表面,影响工件的表面质量。采用自行研制的空气作动器作为执行器,以实现无摩擦接触;采用神经网络-PID控制策略,通过BP神经网络在线学习调整PID控制参数,实现最佳参数组合。实验结果表明气浮溜板的振动主动控制系统是可行性的和有效性的。The influence of aerostatic slide carriage vibration on surface quality of workpice is notable due to direct effect through tool rest in ultraprecision machining, so the study on vibration control of slide carriage is necessary and significant. The active vibration control system of aerostatic slide carriage is discussed in this paper. The air - actuator developed by us is used as actuator for friction -free contact. The controlling method is NN -PID control in which BP neural network is used to implement the optimal combination of parameters of PID control through learning on line. The experimental results show the feasibility and effectiveness of the system.
