| Abstract |
The objective of this paper is to investigate the use
of observers in the sensorless control of induction motor drives.
First, three recently proposed rotor flux and speed observers for
induction motors are analyzed and compared using a unified
notation. Unresolved issues for each method are noted. Then,
an alternative rotor flux and speed observer architecture is
described, which is simulated and tested experimentally. The
conclusion of our study is that observers can perform well
estimating the rotor speed and the estimates can be used in a
control strategy instead of speed values obtained by the sensors. |
