| Abstract |
This paper presents a new sensorless vector control
system for high performance induction motor drives fed by a
matrix converter with non-linearity compensation. The
nonlinear voltage distortion that is caused by commutation delay
and on-state voltage drop in switching device is corrected by a
new matrix converter model. Reduced Order Extended
Luenberger Observer (ROELO) is employed to bring better
response in the whole speed operation range and a method to
select the observer gain is presented. Experimental results are
shown to illustrate the performance of the proposed system. |
