FIELD: electrical engineering. SUBSTANCE: electric drive control signal former 4 is composed by nonlinear converters 5, 6, adders 7, 8 and inverters 9, 10. Electric motor rotor angular position pick-up 12 outputs are connected to adders 7, 8 first inputs by consequent connections of nonlinear converters and inverters. Second inputs of adders are connected with command set up block 11 and finally electric drive smooth control is achievable in full operating range. EFFECT: higher accuracy of frequency stabilizing and electric drive control operating. 1 dwg
