| Abstract |
A kind of speed sensorless sliding – mode
observers for induction motors has been developed. In this
paper a new topology of such observer is investigated in
order to determine its feasibility, robustness to parameter
changes and practical applicability on digital signal
processor. The positive feature of the proposed scheme is
that it doesn’t require the rotor speed feedback or
adaptation, only measured variables such as stator current
and DC voltage are required. Experimental results on DSP
TI LF2407A, presented in the end of the paper show good
correspondence with proposed theory. |
