IDENTIFICATION ALGORITHM OF EXTREME MANAGEMENT BY THE RATTLEJACKS OF SELF-GROWING SHALLOW OF ORES

Abstract

The problem of optimization of ore grinding process in drum mills taking into account the material and its influence on the mill drive system is considered. It is noted that in real conditions there are no ideal conservative control systems for drum mills. Analysis of the movement of the material shows the oscillations of the system, which will either attenuate or will occur with increasing amplitude. Reduction of oscillations is possible using the identification algorithm and is performed in the quasi-stationary conditions of the object, because the time of selection of the necessary information at each control step is much less than the time of decline of the autocorre-lation function of the main perturbing process of physical and mechanical properties of ore. Thus, the model, method and system of extreme control of drum mills of self-grinding of ores are offered in the work.
