LPV Induction Motor Control with MRAS Speed Estimation

This work aims to improve the performance of the control structure of the induction motor. A controller based on the linear parameters varying systems theory and linear matrix equality are used to guarantee stability and robustness for all the operating rangeThe control structure is composed of two loops, the inner one for stator current control and the outer for mechanical speed control and MRAS observer to estimate in real time, rotor speed and rotor time constant. The simulation tests results show the high performances over all the operating range and confirm the effectiveness of our approach.
