Abstract
Structural and parametrical synthesis of automatic control system of initial oil refining technological process on the atmospheric-vacuum distillation unit with the control object with transport delay is performed using the engineering design procedure based on alternance method of parametric optimization. The PI-controller is integrated into the regulation structure in order to compensate transport delay. The PD-controller is used to implement the feedback automatic control system by the control object with the first-order astatism. Adjustment parameters for PI- and PD-controllers are defined using the properties of frequency-response characteristics of the feedback control system; to do this, special control systems are designed which are closed towards the regulator adjustment parameters and resonance frequency of frequency-response characteristics.
