Study of transients in oil pipelines

Consideration was given to the problem of optimal control of the transients at transportation of the hydrocarbon raw stock along the main pipelines. Studied was the dependence of the settling time on the system dissipation coefficient, length of the pipeline section, and the difference between the parameters of the initial and final stable modes under the optimal control of the transients with account for the technological constraints imposed on the control actions and phase variables. Presented were the results of analysis of the dependence of the optimal process settling time on the interval of permissible values defined on various classes of functions for different values of the initial and final stable modes.
