Selection of technical means of automated control systems at the design stage

The purpose of the article is to increase the efficiency of automated control systems (ACS) by optimizing technical means at the design stage. To achieve this goal, mathematical models of the choice of technical means have been developed both quantitatively and qualitatively. The main technical characteristics of the tools used in the automated control system are described. The quality indicators of the automated control system functioning are considered. The formulation of the problem of choosing technical means at the design stage of automated systems, initial data and ways to solve the problem are proposed. Estimates of the effectiveness of using various variants of technological processes in automated systems are given. Based on the obtained mathematical models, the problem of choosing the main parameters of the complex of automated control system technical means is solved. At the design stage, the initial data do not have high accuracy, the restrictions imposed on the reliability and processing time of individual portions of information in various areas are conditions imposed on the mathematical expectations of the corresponding random variables. The availability of these data allows us to proceed to a quantitative assessment of the options used in the automated control system of technical means. In the process of creating a working project, the initial data, algorithms are clarified and the issues of information processing technology in automated systems are analyzed in more depth. Under these conditions, calculations are carried out with the utmost care. Therefore, the restrictions imposed on the timing of solving problems and the accuracy of output information are considered as restrictions on the specified random variables with a certain level of confidence. Taking into account additional limitations, an updated model for calculating the technical means necessary for the design of automated control systems has been developed.
