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.

Algorithmic methods for eliminating interference that affect the accuracy of measuring input signals in measuring channels are considered. Methods for input and processing of signals in the form of currents and voltages in analog modules of measuring channels of the control system are presented. It also considers some ways to improve the classical algorithms of adaptive control implemented on the basis of digital technology, taking into account the conditions for ensuring the stability of a discrete control system.

The article considers the possibilities of algorithmic solutions when creating interfaces based on microcontrollers, which make it possible to reduce the number of mandatory procedures in the organization of multiplex channels with galvanic isolation. The issues of elimination of interferences that affect the accuracy of measuring input signals in the measuring channels are considered. Methods for input and processing of signals in the form of currents and voltages in analog modules of measuring channels of the control system are presented.
