AC induction motors have become very popular for motion-control applications due to their simple and reliable construction. Control of drives based on ac induction motors is a quite complex task. Provided the vector-control algorithm is used, not only the rotor speed but also the position of the magnetic flux inside the motor during the control process should be known. In
most applications, the flux sensors are omitted and the magneticflux phasor position has to be calculated. However, there are also
applications in which even speed sensors should be omitted. In such a situation, the task of state reconstruction can be solved only
from voltage and current measurements. In the current paper, a method based on deterministic evaluation of measurement using the state observer based on the Lyapunov function is presented. The method has been proven in testing on a real ac induction machine.
