FIELD: electrical engineering; reversible drives whose speed is variable within wide range.
SUBSTANCE: proposed method for controlling dc motor includes evaluation of differential output signal as sum of signal equal to increment within tachogenerator output signal modulation and signal proportional to ac component of motor supply current; predicted increment of motor current is generated to be equal to current increment in motor circuit inductance under impact of voltage equal to difference between predicted motor input voltage in respective modulation interval and voltage equal to sum of voltage drop across switching members unit , across active resistance power circuit, and across motor rotation emf.
EFFECT: enlarged functional capabilities.
