The report is devoted to the problem of controlling large robotic complexes of various classes of heterogeneity. Based on the analysis of modern research in the field of robotics, the class of heterogeneity with changing control functions is highlighted. The necessity of systemic integration of control systems of a dedicated class during their operation is substantiated. The basic theoretical statements about the evaluation of the results of system integration are formulated. The problem of a homogeneous hierarchical representation of heterogeneous control systems was indicated. The solutions to this problem are suggested. A quantitative assessment of the proposed options is given. Outlined topics for further research on the problem.
