摘要

This paper presents sensorless control of Permanent Magnet Synchronous Motor (PMSM). In the sensorless control method, the stator current is measured to estimate the speed of the motor. When PMSM sensorless control is used in an electric vehicle, sometimes it causes another problem. When the motor is running in steady state and the motor is suddenly given a large load that has reverse torque direction, it will make a problem. In this case, the large load that is applied is a brake. The motor goes in a wrong orientation. This fact is an undesirable condition. The condition must be controlled so the motor can work well. This issue causes the sensorless control has not really applied to commercial interests. The phenomenon of wrong orientation will be the interest of our research. To predict the speed of the motor, we use Model Reference Adaptive System (MRAS) method as an observer. The IP speed controller is used to control the system. This phenomenon is verified by experimentation in the laboratory.
