  - Przegląd Elektrotechniczny - Year 2024

  This paper focuses on the control strategy for modern universal bidirectional Dual Active Bridge (DAB) converters for microgrid systems. An analysis of the converter equations was carried out, and typical problems related to the influence of dead time on the system operation were discussed. A closed control loop was developed, then tested by simulation and on a laboratory stand.

  - Bulletin of the Polish Academy of Sciences-Technical Sciences - Year 2014

  In this paper the predictive estimation based control strategy for a quasi-resonant dc link inverter (PQRDCLI) is developed. Instead of direct measurement of dc link input inverter current – its estimation with one step prediction is applied. The PQRDCLI fed induction motor, controlled with a predictive current estimation stabilized inverter output voltage slopes independently of load. Moreover, reduction of overvoltage spikes...

• Negative impact of constant RPM control strategy on ship NOx emission in waves

  Publication

  • M. H. Ghaemi
  • H. Zeraatgar

  - International Journal of Energy and Environmental Engineering - Year 2023

  In severe wave conditions, the ship propulsion system is loaded with high fluctuations due to external disturbances. The highly fluctuating loads enforce radical changes in the main engine torque, which in turn demands variation of the fuel rate injected into the cylinders if a constant rotational speed strategy is applied. Therefore, the temperature of gases varies to a large extent during the combustion process in the cylinders....

  - 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...

  - IEEE TRANSACTIONS ON POWER ELECTRONICS - Year 2022

  In the five-phase induction machine (IM), it is possible to better use the electromagnetic circuit than in the three-phase IM. This requires the use of an adequate converter system which will be supplied by an induction machine. The electric drive system described, in this article, includes the five-phase induction machine supplied by the current source inverter (CSI). The proposed novelty—not presented previously—is the control...

  Detailed knowledge on the composition of the influent going into the wastewater treatment system is essential for the development of a reliable computer model. In the context of WWTPs (wastewater treatment plants), the wastewater characteristics are not only important for activated sludge system modelling, but also have an impact on the appropriate control of single unit operations. The aim of this study was to evaluate the concepts...

  Metal-organic frames (MOFs) are regarded as excellent candidates for supercapacitors that have attracted much attention because of their diversity, adjustability and porosity. However, both poor structural stability in aqueous alkaline electrolytes and the low electrical conductivity of MOF materials constrain their practical implementation in supercapacitors. In this study, bimetallic CoNi-MOF were synthesized to enhance the electrical...

• Central heating temperature control algorithm for systems with condensing boilers

  Publication

  • P. A. Kaczmarek

  - Year 2016

  The problem of control of a central heating system in a small residence is considered. It is assumed that the system is based on a condensing boiler. Since the boiler efficiency depends on a returning water temperature, the proposed control goal is to provide proper air temperature in the residence as well as the lowest possible water temperature. The proposed algorithm is applied to two buildings. Both of them have the same heating...

  Praca opisuje zagadnienia modelowania i napędzania robotów kroczących. Na pewnych etapach ruchu, konstrukcje takie są układami napędzanymi nadmiarowo (liczba napędów/silników jest większa niż liczba stopni swobody układu). Dzieje się tak z uwagi na więzy jednostronne występujące w układzie. Dla układów płaskich, po pojawieniu się kontaktu koła i odnóża, układ o sześciu stopniach swobody przechodzi w układ o trzech stopniach swobody....

  Mimo podejmowanych wielu działań w zakresie brd na sieci dróg krajowych w Polsce, rezultaty są dalekie od oczekiwań i zadań postawionych przez Krajowy Program BRD GAMBIT 2005. Można by to tłumaczyć dużym przyrostem liczby pojazdów i wzrostem pracy przewozowej szczególnie na drogach krajowych. Ale porównanie ryzyka występującego na sieci dróg krajowych w Polsce do ryzyka występującego na drogach krajowych najbliższych krajów europejskich...

  W referacie przedstawiono teorię wyjaśniającą zjawisko szumów usznych na gruncie akustyki, elektroniki i telekomunikacji. Spostrzeżenie, że słuch jest w istocie akustycznym układem transmisyjnym, skłania do poszukiwania interpretacji powstawania szumów usznych w ogólnej teorii spontanicznego generowania szumu w układach transmisyjnych. Sformułowana hipoteza wskazuje na istnienie pasożytniczej kwantyzacji, która pojawia się w sytuacji...
