A fuzzy control system design based on double module structure

Abstract

In the high-precision servo system, not only request quickness but also response characteristics without overshoot, usually request strong robot for position loop. The traditional control system design usually is finished under the linear condition which neglects some factors. It makes the more differences between designed model and actual system, so the general PID adjuster and the single basic fuzzy control are different to meet the need. The paper designs a complex fuzzy controller based on double structure and variable coefficient, at the same time adopts Cooperative Processing module with fuzzy reasoning function, which make the system fuzzy reasoning speed improved and realize the online reasoning. So the system capability is improved, the experiment proved the system has the good capability.
