Zusammenfassung:The invention provides an adaptive control method of an electrolytic cell and relates to the field of electrolytic aluminium. The method comprises the following steps of: a first step of analyzing the voltage fluctuating value and the working condition of the electrolytic cell in a certain time bucket during the aluminum electrolysis process, and setting the working condition of a cell controller and an interval value of the alumina concentration; a second step of judging the working condition, and recording the variation, the fluctuating range and the mutation of the voltage fluctuating value of the electrolytic cell in the certain time bucket; a third step of computing the alumina concentration in a certain time bucket according to the initial state and the changing speed of the alumina concentration, and controlling the cell controller of the electrolytic cell so that the working condition of the cell controller of the electrolytic cell and the interval value of the alumina concentration are always optimiz
