In PWM inverter-fed drives, a variation of Common mode voltage (CMV) causes unbalanced voltage operation in induction motor. Multilevel inverters reduce this problem, but the complexity of the power circuit increases with an increase in the number of inverter voltage levels. In this paper, a five-level inverter is compared with two, three and four levels and this five level structure is propose...

In this paper, an enhanced Integral Sliding Mode Control (ISMC) for mechanical speed of Induction Motor (IM) is presented and experimentally validated. The design the proposed controller has been done in d-q synchronous reference frame indirect Field Oriented (FOC). Global asymptotic tracking presence model uncertainties load torque variations guaranteed by using ISMC surface. Moreover, provide...

Deadbeat predictive current control (DPCC) has been widely studied in induction motor drives due to its simple concept, quick response and excellent steady-state performance. However, conventional DPCC uses a lot of parameters predict voltage. Therefore, the performance is affected by accuracy controller. The will severely deteriorate when used controller deviate greatly from their actual value...
