Abstract
Possibility of increase of efficiency of work of induction electric drives which have the stochastic torques of load due to of creation of the closed systems with statistically optimum regulators is shown. Optimal structures of regulators of the electric drives of such class depending on a kind of random loads are defined. Simulation of work of the electric drive of a crusher of grain has shown efficiency of a filtration by statically optimal regulator of the high-frequency components of random torques of load, increase of cyclic indicators of energy efficiency of the electric drive, such as cyclic efficiency and power factor, reduction of dispersions of its outlet parameters - the electromagnetic torque, speed, current.
