FIELD: mining.
SUBSTANCE: system includes a housing, a variable fluid flow conduit disposed inside the housing, an electromagnet connected to the housing, a fluid driven actuator fluidly connected to a variable fluid flow conduit, a load generating unit connected to a drive mechanism controlled by the fluid. The load generating unit comprises a mixing blade and a shaft connected to the mixing blade. The shaft is located in one of the electrorheological fluid and the magnetorheological fluid. The viscosity of the mentioned media can be changed by means of an electromagnet.
EFFECT: reliability of the control system is increased, the accuracy and speed of the turbine rotation control are increased.
