- W2896587645 abstract "The subject matter of the article is the processes of synthesis of the automatic stabilization system (ASS) of the temperature in the vehicle cabin simulator using the vortex energy separator (VES) as the executive element of the system. The goal is to correct element synthesis of the ASS (CEs), which provides stability and quality of stabilization with the intensive change in the thermal load. The tasks to be solved are: to construct the functional scheme of the ASS which consist of the positioning circuit of the modes of the VES and the air temperature stabilization circuit in the cabin simulator; applying the results of solving the problem of synthesis of the automatic positioning system (APS) of modes of the VES, construct the structural diagram and mathematical model of the ASS of the temperature in the form of interval transfer functions (TF); perform the static calculation of the system to ensure the accuracy in steady-state and transient modes with linearly varying input influences; solve the problem of ensuring stability and dynamic levels of quality of the temperature stabilization using interval logarithmic amplitude-frequency characteristics (LAFC) and indirect levels of quality of the system's functioning in the frequency domain. The applied methods are: LAFC, real frequency characteristics. The following results were obtained: the functional and structural schemes of the ASS of the temperature in the vehicle cabin simulator are constructed, the interval transfer functions of the open-loop and closed-loop system are determined according to the referencing and disturbing influences. The static calculation of the system is performed to determine the required value of the transfer coefficient of the open-loop ASS based on the condition of ensuring the accuracy of the system in the steady-state mode of operation and with the intensive change in the thermal load. The dynamic calculation of the system was performed, as a result of which the structure and parameters of the CEs were determined based on the analysis of the dependence of the phase stability margin and the cut-off frequency on the values of the parameters of the CEs in accordance with the requirements for dynamic levels of quality. Conclusions. The scientific novelty of the results obtained is following: the frequency method of synthesis of the ASS using interval LAFC has been further developed by investigating the behavior of the logarithmic characteristics on the boundaries of the intervals of parameters of the transfer function of close-loop APS of the of the VES" @default.
