Application of embedded fuzzy control in frequence conversion and branch drag speed-governing system

Abstract：Frequence conversion and branch drag speed-governing system of print equipment has been studied.It presents dualmodel control means which incorporate indifference Fuzzy control and bang-bang control.It also adopts AVR high speed embedded SCM and achieves the single stage indifference control and fulfill the requirment synchronous pulling of multilevel, It has performed through the on-line measurement of tension.It ensure the tension of fabric that always constant during the system working.The simulation results prove that the system has such control quality as good dynamic, static property, high robustness and reliability.
