Popis:	This paper is devoted to the problem of designing a controlled electric drive of mine hoisting plants on the basis of a doubly fed induction motor. Problems for the developers of this system, particularly identification of immeasurable coordinates of an electric machine, are considered, and methods of solution thereof are proposed. A functional diagram of a frequency-controlled double fed electric drive built using a multilevel frequency converter on the basis of H-bridges is described. An algorithm of sensorless vector control for the case in which only rotor variables, i.e., currents and voltages, are measured is considered. A method of designing a hybrid control algorithm that combines a sensorless approach and vector control with the use of an increment encoder that allows the hoisting mechanism to function at both a zero and synchronous rate of the electric motor. Results of simulation of a multimotor system of an electric drive in the load balancing regime of electric machines are presented.
