Abstract |
A problem of rotor speed and position detection for sensorless PMSM drive was analysed in
the paper. The concept based on detecting back EMF, induced in the stator windings, was developed
and modified. A general structure of observer, with more complex function of corrector than
traditional one was introduced. On the base of this concept the observer with proportional-integral and
sliding mode correction was proposed. Simulation as well as experimental results showed good properties of proposed observer structure. |
