Speed Control of A Doubly Fed Induction Motor using Integral Plus Proportional Controller
Abstract: Conventionally, the speed control manipulate of Doubly-Fed Induction Motor (DFIM) has been developed primarily which is based on traditional Proportional-Plus-Integral (PI) controller due to its simple construction and implementation.

Improvement of Indirect Vector Control Induction Motor Drive Performance under Low Speed Operation using Five-Level Inverter
Abstract: The dynamic performance of vector controlled induction motor drive is poor and peak motor torque decreases under low speed operation. This reduction in torque is due to the non-linearity of voltage to frequency (Hz) during low frequency operation. The non-linearity is caused by stator voltage drop which in turn requires a larger percentage of overall terminal voltage. To overcome these problems multilevel inverter fed induction motor drive is presented in …
