We apply discrete wavelet transformation to decompose the error of motor speed mismatching over various frequency components. Transformed error coefficients together with scaling parameters are utilized for generating of motor control signal. Proposed controller satisfies to problem of speed regulation into closed looped control system. We performed researches the scheme of vector control with wavelet-fuzzy controller under various dynamic operation conditions. Results of comparison between operation of conventioanal proportional integral controller and developed wavelet-fuzzy controller are presented. Simulation results demonstrate efficiency of proposed wavelet-fuzzy controller.discrete wavelet transformationfuzzy logicinduction motorvector controlreliabilityдискретное вейвлет-преобразованиенечеткая логикаасинхронный двигательвекторное управлениенадежность[Виноградов А.Б.
