摘　　要：为了提高微细电火花加工伺服控制系统的精度、实现对伺服间隙的智能控制,提出了以模糊控制算法为基础,通过自调节算法建立合适的目标值,以实现基于模糊控制的BP神经网络在线优化算法,从而提高伺服控制的准确性。同时,采用下位机实现核心控制算法,保证了伺服控制的稳定性和实时性。通过微细电火花深小孔加工实验证明,采用BP神经网络在线优化算法能提高加工精度和加工效率。An algorithm based on fuzzy logic,which can develop proper target values through selfturning and realize online optimization using BP neural network was designed to raise the precision ofthe servo control system of the micro EDM. In addition,this algorithm was integrated to low computer,which can ensure the ability of stable and real time of the control serve system. As the micro holesdrilling process in micro EDM experiment showed,the precision and efficiency of the machining hadbeen improved.
