Industrial Automatic Control Systems and Controllers Annotation << Back Synthesis of a Robust ACS Using an Interval Model of an Object With Delay Lubentsov V.F., Luzhevsky N.O., Lubentsova E.V. A methodology has been developed for constructing robust controllers for control systems for dynamic objects with delay, taking into account the integral assessment of the infl uence of static (object transfer coeffi cient) and dynamic (object time constants) parameters, as well as delay on the robustness of the system. The proposed methodology is based on a reasonable choice of a nominal (calculation) model of an object with boundary values of parameters from the intervals of their change corresponding to their most unfavorable combination, and evaluation of this choice using the criterion of the maximum degree of stability. The proposed method is focused on ensuring the robustness of the system with respect to the parametric uncertainty of the object model while meeting the requirements of speed and overshoot. The research and evaluation of the effectiveness of the proposed methodology were carried out using examples of the synthesis of a control system for an interval industrial facility through a channel for regulating the concentration of dissolved oxygen (pO2) in an industrial bioreactor. The obtained results of an experimental study of the control system of a non-stationary object with a delay showed the effectiveness of the proposed methodology. Keywords: the worst combination of parameters, interval model, maximum degree of stability, robustness, delay, time constants, PID control law. DOI: 10.25791/asu.2.2024.1485 Pp. 03-11.
