T e controller can sync ronously tune t e proportiona,l integral and d ifferen tial param eters on-line according to t e c ange of control value. T e controller was applied to t e re eated steam tem perature control system of a pow er p lant. T e s mi u lation was conducted in cond itions of t e squarew ave re- sponse, object properties variation and noise environm ent. T e results s owed t at t e control strategy ad better con- trol perform ance t an traditional PID and conventional fuzzy mi mune con troller, w ic could get better dynam ic qual-i ty and anti-noise capability, and ad strong robustness and adaptab ility.
