| 英文摘要 |
| Traditionally, the economy of the boiler-turbine system has been handled in a multi-layer hierarchical architecture
where the upper-layer obtains an economical optimal steady state and sends it to the lower-layer for tracking
purpose. However, traditional control structures tend to ignore the economic performance of the dynamic tracking process.
To improve the transient economy, the economic model predictive control strategy based on fuzzy model for the boilerturbine
system is proposed in this paper. The feasibility and stability of the controller is guaranteed through designing the
linear feedback control law and the feasible region off-line. Then, the optimization problem of economic model predictive
control is solved on-line with two modes, i.e., dynamic economic optimization mode and guaranteeing stability mode, so as
to realize improving the economic of the dynamic process. Simulation results under large and small range load variations
show the effectiveness of the proposed fuzzy economic model predictive control. |
