Research on Fuzzy Control Algorithm with Double Parameters Detection of Micro-EDM
In micro-EDM, discharge energy and clearance is very small, discharge state is much complex and changes very fast, so fuzzy control algorithm is put forward. Base on the character of discharging frequency far higher than mechanism response frequency in micro-EDM, taking relative discharge ratio statistical rule as control system’s input, according to error and error change of relative discharge ratio and normal discharge ratio, with manual operation control experience of micro-EDM, fuzzy control rules are designed and fuzzy query tabulation is set up. As result of experiments, when micro-EDM is in condition of low working voltage and small current, fuzzy control system with double parameters detection is proved to improve utilization ratio of pulse, so as to increase utilization ratio, increase working speed and reduce wear ratio of electrode.
