Algorithm for a position sensorless control of a machine

摘要

Control apparatus for an electric motor with a stator and a rotor comprising:a converter for supplying power to the electric motor,a controller for controlling the converter,a block for controlling at low speed of rotation, so that the rotor angular position with the use of the stator current components to estimate, which in the controller operates,a block in order to control at high speed of rotation, so that the rotor angular position with the use of the stator current components and a stator flux estimate position in the controller operates,a switch in the controller via gear operation between the block for controlling at low rotational speed and in the block for the control to change in the case of a high speed,the converter by means of a six stages of operation is controlled.
