FIELD: power industry.
SUBSTANCE: control method of adjustable-blade turbine impeller by servomotor by shifting the main valve from the middle position includes a determination of the current position of the main servomotor, a determination of the deviation of the current position from the set position, used the pulse three-position controller output signal to form the valve offset value from the central position, wherein the input signal is the deviation rate and the signal proportional to this value. An additional signal is formed proportional to the level increace of the specified deviation rate of the current position of the servomotor from the predetermined one which rate is selected in accordance with the speed determined by the calculation of its positioning accuracy at deviations selected to control its movement by the controller only. The amount of the additional signal and the controller output signal is used as a valve displacement signal.
EFFECT: improved reliability of the impeller blades drive.
