摘要：AbstractIn order to optimize the economic objectives while regulating the ultra-supercritical boiler-turbine unit, an improved utopia tracking based multiobjective fuzzy model predictive control is proposed in this paper. This method uses a hierarchical structure, in which the quasi-infinite horizon fuzzy model predictive control is designed for the steady-state compromise point in the upper layer and the utopia tracking based multiobjective control is devised in the lower layer. To ensure the closed-loop stability, a constraint with respect to the optimal value function about the compromise point is enforced. The simulation results on a 1000MW USC boiler-turbine unit model verify the merits of the proposed strategy in achieving less fuel consumption and less throttling loss during the load regulation.
