Improvement of Position Controller Based on Fuzzy Neural Network Performance

With the modification of laser sub-marker controlling system, the intelligent harmony close-loop position servo system is designed in this article, which meets the requirement of high performance in position servo system. It bears the advantage of fuzzy controlling and nerve network controlling technology, and it weakens the influence on the system from non-linear factors. Thus the design improves the position accuracy of servo motor and position tracing, which guarantee the precision of three-dimension laser processing system.
