Simulation of Stochastical Dynamic Objects with Periodical Action

The article deals with determining the operating quality of stochastic dynamic systems in transient modes. Such problems are encountered in the mechanisms of periodic action in the processes of drying, ventilation, heating, etc. Stochastic differential equations are used to determine the dynamic characteristics of control objects whose initial state is a random variable and the input signal is a random process. As an example in the article, a stochastic dynamic model of the active grain ventilation hopper is constructed; the required technological process duration that ensuring the desired product quality is determined.
