Analysis of the Impact of Changes in System Parameters on the Quality of Control
Authors: ,
Abstract: This article addresses the problem of processing hardware and software interrupts in the Siemens PCS7 distributed control system as part of industrial process control with a multitude of control objects. Problems of processing asynchronous requests for elements of control systems on the interruption of a periodic regulatory cycle will also be described. These requests increase the processing time of information, which can disturb the stability of the automatic control system. The article presents the normalized mathematical model of the regulatory system and the method for analyzing the robustness of this system.
