Zusammenfassung:	The embodiment of the invention provides a PI controller based on adaptive speed measurement and a control method and system thereof, and belongs to the technical field of adaptive speed measurement. The control method comprises the steps of obtaining a current estimation value of an adjustable model and a current actual value of a reference model; and obtaining a current error value according to the current estimation value of the adjustable model and the current actual value of the reference model. According to the technical scheme, the PI controller based on adaptive speed measurement and the control method and system thereof provided by the invention have the advantages that the current error value and the change rate of the current error value are calculated by acquiring the current estimation value of the adjustable model and the current actual value of the reference model; and the fuzzy controller intelligently adjusts the output value according to the current error value and the change rate of the cur
