Abstract

This paper deals with a comparison study of currently provided PI control system and the new proposed fuzzy control system for superheated steam temperature control of high pressure part in the power plant once-through boiler Fuzzy control properties are verified by simulation experiments for operating modes such as load level step and trend changes. Nonlinear model is used for the simulation experiment. The important fact, in terms of control algorithms implementation, is verification of control system properties during the change of process dynamics and response to disturbances. The response of fuzzy control system and original PI control system response are compared. Fuzzy control results dramatically improve system responses.
