| 英文摘要 |
| In-line blending of gasoline is a complex, multivariable, nonlinear process with strong uncertainty and large time-delay. For this processes, we propose an advanced control strategy which consists of a dynamic-matrix-control (DMC) part to deal with the large delay caused by the on-line octane analyzer, and an expert octane controller for calculating the flow of blending gasoline in each batch. The proposed control strategy performs a precise control of the octane quality of the resultant gasoline, thus reducing the blending cost. The designed strategy is applied to a practical in-line blending process in a refinery. Simulation and experimental results demonstrate such advantages as high-precision control for the octane quality of the resultant gasoline, strong robustness to various uncertainties, etc. It is expected that the designed
control system will bring economic benefit for refineries by largely reducing the blending cost. |
