摘　　要：设计电火花放电状态分类统计法,用MATLAB生成模糊控制函数,并用存储器查表法实现模糊控制器硬件化.硬件化的电火花伺服进给模糊控制器,是在Altera公司EP1C12Q240C8可编程逻辑器件中实现的,占用760个逻辑单元,40 960个存储比特,模块工作频率可达72MHz.仿真结果表明:控制器计算迅速,几乎不消耗时间,完全能满足电火花数控系统的实时性任务要求.A statistical method for various types of electric spark discharge status was designed. A fuzzy control function with MATLAB was generated and the hardware-based fuzzy controller with memory look-up table scheme was established. The hardware of the electrical discharge machining （EDM） servo fuzzy controller is implemented in the Altera Corporation＇s programmable logic devices EPIC12Q240C8 with 760 logic cells and 40 960 memory bits, the module operating frequency of which is up to 72 MHz. The simulation results show that the fuzzy controller is of high efficience, almost no time-consuming, which is fully able to adapt to the real-time EDM CNC tasks requirement.
