Industrial Automatic Control Systems and Controllers Annotation << Back Математическая модель процесса дробления щебня в автоматизированном дробильном производстве А.Г. НАДИРОВ (МАДИ) A mathematical model of macadam size sampling from normal distribution is considered based on assumption that, during the crushing, the size values are concentrated around the mean value. The concentration process is formalized by using the properties of the so-called conjugate families of distributions. An example of optimal automated control of a jaw crusher is cited.
