Abstract

The aim of this paper is to present the method of sensorless startup of super high speed permanent magnet motor. Two types of control methods are taken into consideration. In the first part of the startup the current mode as a control strategy was used. In this article the mode of switching the control strategies from the current mode to the vector control is proposed. The extended Kalman filter (EKF) and the unscented Kalman filter (UKF) were used in the vector control for angular velocity estimation. There is also presented the influence of accuracy of the voltage distortion compensation on the control quality.
