The article analyzes an unified system of results of state geoecological monitoring at a gas field in southern Uzbekistan, highlights problematic geoecological aspects in the exploration and development of gas fields of this system, and explores the legal basis for the activities of subjects of the state environmental monitoring system. The necessity of changing and supplementing the legislation is indicated for more effective management of nature and ensuring geoecological safety with the help of the Geoenvironmental monitoring system. The necessity of creating a regional system of geoecological monitoring is substantiated and equipped with modern software for online monitoring of the state of the environment in Surkhandarya region.

Adaptability analysis of linear continuous control systems with reference model

The problem of analyzing the tuning parameters of linear continuous controllers related to the class of state models is studied. To do this, algorithms for adjusting the controller are used, which are based on estimates of the plant parameters. Within the framework of this study, the adaptability property of the system is considered, and the primary goal is to determine the possibility of finding an exact solution to the problem of tuning the control loop for a given reference transient. Moreover, the study extends to a whole class of input actions, such as piecewise continuous functions of time. Based on the analysis of the convergence properties of the identification residual in a closed control system, additional simplified conditions for the adaptability of control systems using an identifier and a reference model are put forward, which supplement the already existing knowledge on this topic.

“…But the Kotelnikov series is not very convenient, in comparison with other series, in software and hardware reconstruction, which most often determines the choice in favour of power series, Lagrange polynomials, etc. [10][11][12][13][14][15]. In the proof of the sampling theorem it is assumed that an infinite Kotelnikov series is used to recover the information.…”

Filtering errors in primary sensor signals

Jumaev,

Ismoilov

2023

Sensors are used in the primary measurement of signals. When signals in the sensor are transmitted to the next device, there is an occurrence of errors due to various effects. Filters are used to eliminate the errors that have occurred. Depending on the frequency nature of the signals, there are high pass filters and low pass filters. We select the filters according to the frequency range of the signal. It is observed that the measurement result is different from the actual value if the signal is not filtered. This article analyzes the errors that occur when signals are processed. In time discretization, the state of the signal spectrum is considered. The cause of the appearance of errors has been studied.
