摘要：In this pa.er a.tria. ha. been ma.e to design a.simple self-tuning La.VIEW-ba.ed PID controller. The controller uses a. open-loop rela. test, ca.cula.es the tuned pa.a.eters in a. open loop mode of opera.ion before it upda.es controller pa.a.eters a.d runs the process a. a.closed-loop system. The controller rea.ts on a.persistent offset error va.ue a. a.result of loa. disturba.ce or a.set point cha.ge. Pra.tica. results show tha. such a.controller ma. be recommended to control a.va.iety of industria. processes. a.GUI wa. developed to fa.ilita.e control-mode selection, the setting of controller pa.a.eters, a.d the displa. of control system va.ia.les. GUI ma.es it possible to put the controller in ma.ua. or self-tuning mode.
