Was proposed method for structurally-parametric synthesis of control laws for n-order nonlinear objects with functional uncertainty on state and control. Moreover, control objects may have an unstable state of equilibrium, and their output matrix may contain right eigenvalues.The algorithm of structural synthesis of the proposed method is based on setting the law of derivative change n-th of state`s variable of synthesized automatic control system, applying of operator-parametric feedback on the calculated inversed undefined gain coefficient value of control object and usage an observer of state`s variables and of a compensating coupling on the deviation of the state`s vector of the synthesized and etalon system.
