The invention discloses a dynamic optimizing control method for the efficiency of a high capacity oil transfer pump, comprising the following steps: firstly, the setting value of an oil transfer pump system is assured, the actual output value of the oil transfer pump system is measured, a deviation value signal is inputted into a network controller, wherein, the deviation value is equal to the setting value deducts the actual output value; secondly, an output value is transmitted to the oil transfer pump system after being counted by the network controller, the change of a centrifugal pump parameter is realized, meanwhile the output value and the actual output value of the oil transfer pump system are jointly inputted into an identification network by the network controller, and the identification network is modified by a deviation value between the identification output value of the identification network and the actual output value, therefore, the identification output value is closeto the actual output value; and finally, according to the deviation situation between the setting value and the identification output value and the relationship between efficiency and the actual output value, the parameter of the network controller is modified by a system optimization purpose process so as to realize dynamic optimizing control and cooperative control for the efficiency of the oiltransfer pump system.
