Improved Direct Torque Control of Induction Motor for Torque Ripple Minimization

A new direct torque control (DTC) method of an induction motor (IM) which minimizes ripple $\left ({T_{ripp} }\right)$ while preserving all the conventional DTC advantages is presented in this paper. Large notation="LaTeX">$T_{ripp}$ and current are main drawbacks DTC. To address problem, paper gives a qualitative analysis sources novel strategy to reduce constant notation="LaTeX">$T$ field weakening (FW) regions proposed. The performance proposed evaluated compared with recently published that aims for same goals pursued paper, as well has been carried out on basis results obtained by theoretical hardware implementation.
