Speed sensorless mixed sensitivity LPV H_inf control of the induction motor

TL;DR: The paper shows the design of a robust control structure for the speed sensorless vector control of the IM, based on the mixed sensitivity linear parameter variant (LPV) H_inf theory, which shows good dynamic and robust performance.

Induction motor current controller for Field Oriented Control using Individual Channel Design

TL;DR: In this article, a control strategy for the design of an induction motor stator-current controller is presented, which is based on a controller which is linear, diagonal, low order, stable, minimum phase and time-invariant.
