based onvoltage model (7) and (8). Since (5) and(6) do
not involve the rotor speed w,, it may be regarded as a
reference model; (7) and (8), involve w,. , may

the measured rotor speed and the estimated rotor speed
are presented. Fig.6 shows the estimated rotor flux.

die gemete rotor spoed en die beraamde rotor spoed
aangebied word. Fig.6 toon die geskatte rotor vloed.
