One of the promising directions in the development of an electric servo drive systems is the use of a hybrid stepper motor without a rotor position sensor in precise positioning systems. A procedure for synthesizing an algorithm for controlling an electric servo drive based on a hybrid stepper motor is considered. A method is proposed for switching the windings of an operating motor, which makes it possible to exclude resonance phenomena in the drive power system. An algorithm for vector control of the torque of a stepper motor is developed using the algorithm for observing the speed and angle of rotation. A simulation model of the electric servo drive with vector control and adaptive speed observer has been developed in the package Simulink. The effectiveness of the proposed methods for controlling the operating motor is confirmed by the results of dynamic modeling.
