Abstract :
A practical solving method for nonlinear blending system (NBS) based on hierarchical fuzzy control is proposed. The solving method can reduce the required rule base size by using the hierarchical fuzzy control, and increase the robustness and response performance of NBS. In order to confirm, the proposed solving method is used in ethanol gasoline blending system in tank farm of PetroChina and SINOPEC. The control precisions meet the requirement of distributing and blending. It avoid that the electro hydraulic valves regulate frequently by using this method. The cost of NBS has been down. The system and approach proposed is applicability in other petroleum chemical control system.
