  • Advances in CSI-fed induction motor drives

    Publication

    The application of current source inverters (CSI)in induction motor (IM) drives offers a number of advantages,including: voltage boosting capability, natural shoot-throughshort-circuit protection and generation of sinusoidal voltages.The exact generation of sinusoidal voltages is possible thanks tothanks to the effect of the output ac filter capacitors and mayimprove the accuracy of sensorless IM control. The eliminationof high...

  • Over-Voltage Studies in Inverter Fed Induction Motor Drives

    Publication

    - Year 2007

    W pracy przedstawiono metodę identyfikacji pojemności pasożytniczych uzwojeń silników asynchronicznych uwzględniającą ich rozłożony charakter. Przedstawiony szerokopasmowy model obwodowy uzwojeń silnika asynchronicznego pozwala na modelowanie zjawisk przepięciowych w silnikach asynchronicznych, w szczególności zasilanych poprzez przekształtniki energoelektroniczne. Zaproponowana metoda analizy umożliwia również określanie składowych...

    - IEEE JOURNAL OF EMERGING AND SELECTED TOPICS IN POWER ELECTRONICS - Year 2014

    In this paper, we present a new approach based on discrete Fourier transform (DFT) analysis for controller tuning of the closed-loop system with unknown plant. The DFT analysis is used to process the closed-loop measurements collected online to derive the frequency response of an initial closed-loop system that does not provide a good performance. Based on the closed-loop frequency response data, we propose two methods for tuning PID...

  • MRAS-Based Switching Linear Feedback Strategy for Sensorless Speed Control of Induction Motor Drives

    Publication

    - ENERGIES - Year 2021

    This paper presents a newly designed switching linear feedback structure of sliding mode control (SLF-SMC) plugged with an model reference adaptive system (MRAS) based sensorless fieldoriented control (SFOC) for induction motor (IM). Indeed, the performance of the MRAS depends mainly on the operating point and the parametric variation of the IM. Hence, the sliding mode control (SMC) could be considered a good control alternative...

  • Open-Phase Fault Detection Method for Sensorless Five-Phase Induction Motor Drives with an Inverter Output Filter

    The paper presents the sensorless five-phase induction motor drive implementation with an inverter output filter with third harmonic injection. For the sensorless operation, the required observers are presented for the first and third harmonics with consideration of the inverter output filter. Moreover, the interaction of the observers and the control system is capable to handle a deactivation of one or two phases, which improves...
