On-Line Coordinative Fuzzy Control of Active Leakage Control System for Power Station Boiler

Abstract For leakage problem of air preheater in large power station, a distributed and hierarchical fuzzy control system is presented in this paper. In each local processor unit, a kind of distributed fuzzy control rule is used. In order to maintain performance of whole system, the coordinative controller is necessary. Data come from local processor units are transmitted by the communication interface. Depending not only on these data but also on the human experience, coordinative controller coordinates the local processor units and makes the leakage of air preheater reduce largely.
