Abstract:
A im ing at the prob lem s of the long tim e lag, nonlinearity and the prec isem athem aticm ode l that is ha rd to build, w e consider com bin ing the advanced inte lligen t contro lw ith the trad itional autom atic instrum ent to realize low co st autom atiza tion. A ccording to the pr inc iples o f fuzzy contro l and the features o f PLC, the pape r presents am ethod of rea lizing fuzzy contro l based on the PLC, and suggests a design and ladder program of the fuzzy contro ller based on S iem ens S7- 300 PLC. The effec tive contro l fo r the three-steps w ater tank plan t has been realized on the exper im enta l insta llation. The exper im ent resu lts ind icate that the fuzzy contro l system is re liable and effic ient in ope rating and thus better than the traditiona l PID control in perform ance.
