Speed Observer for AC Induction Machine Sensorless Control with Stator Resistance Estimation
Blaha Petr, doc. Ing., Ph.D., CAMAT (FEKT)
Control of drives based on AC induction motors is a quite complex task. Provided the vector control algorithm is used we need to know not only the rotor speed but also the position of the magnetic flux inside the motor during the control process. Flux position is usually estimated, but there are also applications in which even speed sensors should be omitted. In such a situation, we have to solve the task of state reconstruction only from voltage and currents measurements. In the current paper, we present a method based on Lyapunov stability analysis improved with stator resistance estimation. The method has been proven in testing on real AC induction machine.
