Addressing the issue of «complexity» and «perplexity» categories is caused by the evolution of system types ranging from well-organized to self-organizing, expanding the horizons of scientific rationality. Development of governance systems is revealed through the dichotomy of properties and restrictions within the «organizational set-up» and «external influence» notions. It was shown that the governance system falls into the category of complexity because the system is operating on the edge of «order and chaos». External environment is presented as chaos analogue showing uncertainty and changes of various fluctuation category, up to turbulence. The incorporation of social and economic system into external environment was considered from the perspective of formation of «system convergence» of two open systems, contributing to growth of the degree of complexity of governance system. It was emphasized that business development forces perplexity governance systems to switch to robust control; the mechanism of robust control is organized under the influence of the laws of evolution and survivability of biosystems. The following methods were marked out and justified: selection of parameters for system convergence of governance system with external environment entities, determination of limits of information granules of adaptive and robust homeostasis, scenario planning, construction of convergent strategy and temporal attractor of system equilibrium state, known as «floating equilibrium». These methods are to be mastered by the governance system within robust control.
