“…This concept which is known as the coupled state dynamics of IMD which causes the main drawback for high power drive performance applications. In case of a DC motor, the response characteristics for flux and torque are better than the inductor motor, but DC motor applications are limited because of various factors (Adireddy et al , 2022; Bhimireddy et al , 2021; Nadh and Rahul, 2022; Usha et al , 2022; Xiao et al , 2020).…”

Purpose The purpose of this study is to provide the enhancement of power quality of a high power-rated voltage source inverter driven induction motor with a three-phase, three-level neutral point clamped converter placed at the front end, while a passive power filter is connected in shunt with it. The improvement in power quality can be achieved by reducing the total harmonic distortion in source current. The controllers were designed for the linearization of the high-power induction motor drive. A control method is presented for the regulation of the common DC-link voltage. Design/methodology/approach The induction motor is modeled using its dynamic equations, and a decoupling controller is designed to linearize the nonlinear dynamics of the drive through feedback. The common DC-link voltage of the proposed front-end connected converter is monitored and controlled through a control method which feeds the pulse width modulated inverter that drives the induction motor. A passive power filter is designed to meet the reactive power requirement of the system in addition to improve the power quality. Findings Simulations were carried out for the proposed topology of the drive mechanism, and the outcomes were analyzed by a comparative analysis of the drive system both in the presence of the passive filter as well as in the absence of the filter. The total harmonic distortion is found to be reduced enough to meet the standards with the designed filter, and the reactive power is also compensated considerably. The input power factor at the supply side is maintained almost to unity, and the DC-link voltage of the proposed circuit topology is maintained at the desired level. The overall performance of the drive system was found to be useful and economical. Originality/value A new topology of a front-end connected three-level neutral point clamped converter to a high power-rated induction motor drive is proposed. The drive is fed by a pulse width modulated inverter with a common DC-link with the front end connected converter. A passive filter is designed with respect to the reactive power requirement of the system and connected in shunt to the converter at the supply side. Control schemes are designed and used for the drive system and also for the regulation of the common DC-link voltage of the proposed front end connected converter.

“…This two-phase process involves the approach phase, where the system approaches the sliding surface, and the glide phase, where the system maintains its position and smoothly slides along the surface. The sliding mode controller's effectiveness lies in its ability to handle uncertainties and disturbances, ensuring stable and reliable control even in challenging operating conditions [13], [14], [15], [16].…”

This paper introduces a neural network adjustment method for a single gain of an IP speed regulator, to improve the speed control of an induction motor. Thanks to its simplicity and strength the (IP) controller is widely used in the industry for speed control. Yet, in some cases, when the load or mechanical parameters change according to its working conditions, the IP efficiency decreases and the setup quality degrades. In this case, a neural IP-self-tuning seems to overcome these difficulties and ensure a good control performance. The results obtained through the implementation of the proposed control on a dSPACE system and an induction motor clearly demonstrate the effectiveness of this method.
