| Abstract |
This paper presents a solution for rotor speed and position detection in permanent magnet
synchronous motors, suitable for application in sensorless control schemes. The approach is based on
the estimation of the motor back-EMF through a Sliding Mode Observer and a Kalman filtering. Due
to its characteristics, the method is suitable for application in isotropic motors having unknown and
whatever shaped back-EMF waveforms. After a brief exposition of the back-EMF model and the
explanation of the detection technique, simulation results showing the performance during transient
and steady-state operation are presented. Particularly, low speed operation and motor start-up are
tested, which are the most critical conditions in back-EMF based sensorless schemes. |
