Improved double-layer structure model predictive control method for oil and gas pipe network system

The invention discloses an improved double-layer structure model predictive control method for an oil and gas pipe network system, and relates to the technical field of process control of the oil and gas pipe network system.The method comprises the steps that a target function of an economic optimization problem is constructed for steady-state manipulated variables in the oil and gas pipe network system; constructing a constraint condition of the steady-state manipulated variable and a constraint condition of increment of the steady-state manipulated variable; constructing a constraint condition of a steady-state stable type controlled variable and a constraint condition of a steady-state integral type controlled variable; constructing a constraint condition for ensuring the steady-state integral slope of the steady-state value of the steady-state integral type controlled variable in an operable interval; solving the objective function based on all constraint conditions; and taking the steady-state target of
