The use of fractional standard forms expands the range of possible settings of fractional regulators in the synthesis of electromechanical systems (EMS) circuits, provides better quality of transients compared to regulators of the whole order and thus increases the efficiency of synthesized systems. Studies of various variants of parametric synthesis of PIλDμ -fractional speed controller for the system "Frequency Converter - Asynchronous Motor" (FC-AM) using intelligent control methods, including genetic algorithm, showed the full efficiency of this approach. The analysis of the use of different methods of approximation of the desired transfer function (TF) of fractional order with a characteristic polynomial in the form of a two-term fractional degree showed the feasibility of using chain fractions to solve this problem. Computer researches of algorithm and programs of realization of differentiating and integrating links of fractional order, as components of PIλDμ - regulators have shown efficiency of application of approximation of TF of fractional order. The application of the rational fraction decomposition theorem allowed to construct structural schemes from parallel connected aperiodic units for the realization of approximated TF of arbitrary order. It has been experimentally proved that the implementation of fractional order regulators based on approximated TF can work in real time as part of highly dynamic automatic control systems. Tests of the MFC 710 inverter option with PIλDμ - fractional order controller in the speed control system using the Twerd stand have confirmed its effectiveness in terms of expanding the control capabilities of such an electromechanical system.
