The rapid advancements in induction motor drives has led to the development of robust non-linear controller such as Fuzzy Logic Controller (FLC). The proportional integral or derivative controllers (PI, PID, and PD) have been in use for induction motor drives for past decades as speed and current controller's. However, these controllers are fixed to motor parameter changes which results in decrease...
In industrial electrical drives has been traditionally employed the technique of analysis the technique of analysis of vibration to detect misalignment between the motor axes and the load. This technique requires the placements of sensors directly on the drive, which makes it difficult to apply. In some cases, it may be impossible to apply (submerged or hard access drives). Recently, as complement...
