Abstract

This paper presents a sensorless control strategy for induction motors using low cost electrical sensors. The main contribution is the use of low-cost electrical sensors. It is allowed thanks to the use of a linear Kalman filter. To achieve state estimates as close as possible to the optimal ones it is also presented a procedure to perform the tuning of the Kalman filter. A robust model reference adaptive controller (RMRAC) is used to perform the tuning of a model reference controller (MRC) that controls the induction motor despite unmodeled dynamics
