FIELD: nonferrous metallurgy.;SUBSTANCE: the invention presents a method of an automatic control of technological state and failures of the aluminum electrolyzer and is dealt with the field of nonferrous metallurgy, in particular, with electrowinning aluminum. During the automatic control of technological states and failures of the aluminum electrolyzer they measure the amplitude of oscillation of an operational voltage within the range of frequencies and the amplitude of oscillation of a current in the train. Then calculate the adjusted value of voltage, compare it with the given values and pinpoint the technological failures. They form a time train of the adjusted voltage in the range of frequencies of 0.005-1.0 Hz. Additionally they make amplitude-frequency transformation of the signal. Classification of the results of the transformation is carried out with the help of an artificial neuron network. The results of classification are compared with the types of technological states and failures of the electrolyzer. The invention allows to increase the information density, accuracy, speed of operation and to define a bigger number of the technological states and failures of the electrolyzer.;EFFECT: the invention allows to increase the information density, accuracy, speed of operation and to define a bigger number of the technological states and failures of the electrolyzer.;6 cl, 4 dwg, 3 tbl
