Design of Pulse Generator and Intelligent Controller for Micro EDM

This paper designed a micro EDM pulse generator used DSP and CPLD as the control unit,which can satisfy the requirements that the micro EDM single pulse energy must be small and controllable.According to the problem that mathematical model of machining process is difficult to build,we designed a fuzzy neural network controller,because intelligent control has the advantages that it does not depend on the mathematical model,so we can adjust the online parameters in real time according to the gap state.The micro hole machining experiment shows that the processing method of intelligent control can improve the processing speed,which has a good apply prospect.
