To obtain the logical and temporal characteristics of the model of control loop process variable, an analysis of the subsystem hardware of the autonomous unmanned object onboard control system was conducted. The problem of time delays in the information transmission from the primary converter to the control element in automated process control systems is considered as equivalent of the subsystem of the onboard control system of an autonomous unmanned object. At present, there are no methods for estimating the effect of time delays of an information signal on the response time of a control loop, which leads to inefficient use of system resources. The increased time interval between the change in the process variable and the control effect can also lead to negative consequences. Parametric identification of individual nodes with subsequent compilation of a closed loop model by a separate parameter is selected as a tool for system analysis.
