Algorithm For The Synthesis Of The Control System Of A Double Mass Elastic Dynamic Object, Isomiddin Khakimovich Siddikov, Gulchekhra Rakhimjonovna Alimova, Davronbek Abdalimovich Khalmatov
Chemical Technology, Control and Management
There are dealt with the creation of a control system for a dynamic object with an elastic property, described by a system of second-order differential equations, further transformed into two polynomial equations in matrix form in a paper. In order to solve the problem of synthesizing the control system, two matrix polynomials with unknown parameters were introduced into the system of equations, which is the transfer function of the controller, the order of which is two, giving the system the properties of astatism. To solve the delivered problem posed, the matrix polynomial equation was transformed into a matrix linear equation …

Chemical Technology, Control and Management
The main goal of this work is to obtain a preparation of acetamizole based on local raw materials by a more convenient method of acylation of 2-methoxycarbonylaminobenzimidazole with glacial acetic acid, this synthesis method is proposed for the first time. On the basis of the conducted experiments, favorable conditions for the reaction were found, the influence of the nature of the acid, the temperature, the duration of the reaction and other factors on the course of the reaction was studied, the technology was developed and implemented at the experimental production of "IHRV AN RUz". Based on experiments conducted by scientists …
Steady Algorithms For Synthesis Of Multidimensional Controlling Systems With Incomplete Information About The Object State, Uktam Farkhodovich Mamirov
Steady Algorithms For Synthesis Of Multidimensional Controlling Systems With Incomplete Information About The Object State, Uktam Farkhodovich Mamirov
Chemical Technology, Control and Management
In this paper, questions of forming and creation of steady synthesis algorithms of multidimensional controlling systems at incomplete information on object status are considered. It is shown that the matrix of feedback coupling on a status at the complete information is not determined. The different algorithms of steady calculation of a matrix pseudo-inverse to the matrix of outputs using these or those decomposition of matrixes are analyzed. Algorithms of iterative specification of a required solution of "skeletal" decomposition are given. The given expressions allow synthesizing the simplified computing procedures of synthesis of multidimensional controlling systems at incomplete information on object …
