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)...
The aim of this paper is to present the method of sensorless control of super high speed permanent magnet motor. The extended Kalman filter (EKF) is considered as the speed observer and some aspects of using it (including tuning the covariance matrixes) are presented in the paper. The start-up process as well as the steady state is taken into consideration.
The aim of this paper is to present the method of sensorless control of permanent magnet motor operating in high speed. The paper shows the comparison between two versions of extended Kalman filter (EKF) used as the observers. The start-up process as well as the steady state is taken into consideration.
