The present invention discloses a non-linear analysis method based online intelligent identification method for a flow pattern of a gas-solid fluidized bed. The method comprises: performing sampling and analysis of a pressure pulsation signal on the gas-solid fluidized bed and extracting a feature value; performing objective clustering by means of a fuzzy cluster algorithm according to the feature value and the pressure pulsation signal; and establishing and training a flow pattern identification system according to the pressure pulsation signal, the feature value and an objective clustering result, and embedding the system into a computer to implement online intelligent identification of the flow pattern of the gas-solid fluidized bed. The method can avoid the influence of subjective factors on flow pattern identification accuracy, and perform dynamic analysis and flow pattern identification on a transient state parameter.
