In this paper, an intelligent coordinated control scheme for a fossil-fuelled drum boiler-turbine plant is presented. It consists of a two-level hierarchical control strategy. At the supervisory level, a fuzzy reference governor generates the water level set-point deviations during load rejections according to a fuzzy rule-based policy. At the control level, a robust control system via LQG/LTR is implemented. The performance of the proposed fuzzy supervisory control system is demonstrated by simulations under various conditions and results are compared to those obtained by only considering the robust controller without the supervisory reference governor
