The article considers lacks of the servo drive with the asynchronous actuating motor, representing a traditional system of vector control. To increase the electric drive’s response-time speed it has been offered to apply a four contours system with current contours, the speed and two position contours. In the current contour, the traditional regulator has been applied, and in the contour of speed – proportional-differential contour has been used. The internal contour of position contains a proportional regulator, and the external – the integrated one. During the parametrical synthesis of regulators, the new specially developed technique based on formation of a pole of transfer function of the closed contour of the demanded size has been applied. Analytic formulas for the calculation of constants of time and factors of regulators’ transfer on the known technical characteristics of the asynchronous actuating motor, the power converter and the sensors of feedback have been driven. By means of computer modeling it has been shown that the offered servo drive with the asynchronous actuating motor and the technique of the regulators parameters choice provide a high speed response-time at optimization of the operating influence at monotonous character of the transient.
