# THE METHOD OF HIERARCHICAL MACROMODELING FOR ANALYSIS OF MULTIDIMENTIONAL AND MULTICONNECTED AUTOMATED CONTROL SYSTEMS

The application of the method of hierarchical macromodeling for the analysis of multidimensional and multiply connected automated control systems is considered. A macromodel is a mathematical model that corresponds to the basic parameters of a projected object. One of the features characteristic of complex objects is the presence of loosely connected subsystems. For each subsystem, the input and output phase coordinates to be analyzed and the variable parameters are explicitly distinguished. The elimination of internal variables from each subsystem provides a significant reduction in the number of equations of the original model. The construction of hierarchical macromodels for mathematical models of such objects is possible due to the independent construction of macromodels of subsystems with their subsequent integration. The analysis is carried out by the method of frequency characteristics on the basis of block hierarchical macromodels. The possibilities and advantages of the proposed method are shown in the example of a multidimensional and multiply connected control system of a triaxial gyrostabilizer.
