FIELD: power engineering, electronics.
SUBSTANCE: proposed method and device exploit modulation algorithm. Proposed device incorporates preliminary control signal computation device to rise power plant output signal to designed value, device to divide aforesaid preliminary signal into multiple components, modulator to modulate at least one of aforesaid components and adder to sum modulated component with other components to generate input control signal. This allows minimising input signal pulsations caused by modulation, compensating nonlinearity of power plant characteristics, e.g. friction and hysteresis brought about by traditional modulation algorithm, and eliminating input signal variations.
EFFECT: compensation of nonlinear characteristic of power plant, higher stability of power plant with high pulsation of control variables.
