  • H. Abu-Rub

  - International Journal of Engineering Science and Technology - Rok 2010

  W artykule przedstawiono układ napędowy pojazdu elektrycznego wykorzystujący niezawodny i tani silnik prądu przemiennego. Zastosowany trójfazowy silnik asynchroniczny klatkowy wymaga zasilaniaz falownika napięcia przekształcającego napięcie stałe z akumulatorów na napięcie przemienne. Wykonany tranzystorowy przekształtnik sterowany jest mikroprocesorowo. Zastosowany procesor realizuje algorytm sterowania polowo zorientowanego,...

  • W. Kulesza

  - CONTROL ENGINEERING PRACTICE - Rok 2017

  This paper presents a sensorless algorithm designated for the emergency control of an interior permanent magnet synchronous motor (IPMSM) drive in electric or hybrid vehicle. The algorithm is based on analysing the derivatives of motor phase currents measured over the duration of particular inverter states. The method is computationally simple and does not require additional hardware since the derivatives are measured indirectly....

  - Rok 2020

  Vehicular ad hoc networks (VANETs) have recently gained noticeable attention due to advantages in improving road traffic safety, shaping the road traffic and providing infotainment opportunities to travellers. However, transmission characteristics following from the IEEE 802.11p standard and the high mobility of VANET nodes remarkably reduce the lifetime, reach and capacity of wireless links, and often lead to simultaneous disruptions...

• Losses and energy efficiency of drive motors and systems

  Publikacja

  • Z. Paszota

  - Polish Maritime Research - Rok 2013

  Losses and energy efficiency of every drive motor must be presented as functions of physical quantities independent of losses in the motor. Such quantities are speed and load required by the machine or device driven by the motor, changing in the drive operating field. Speed and load of the motor decide of the instantaneous useful power of the motor and also in a differentiated way of kinds and values of losses occurring in the...

  - MATEC Web of Conferences - Rok 2019

  Key to understanding the needs and tools of road infrastructure management for preventing run-off-road crashes or minimising their consequences, is to identify the hazads and sources of hazards caused by wrong or improper use of road safety devices and identify errors in the desifn, structure, construction and operation of road safety devices. Studying such an extended scope of the problem required fieldwork and surveys with road...

• Assessing vehicle restraint systems on horizontal curves

  Publikacja

  • M. Budzyński
  • D. Bruski

  - MATEC Web of Conferences - Rok 2018

  Horizontal curves, an element of road infrastructure, have a statistically high number of accidents. Considering that horizontal curves in the last ten years have had app. 10% of all road accidents representing app. 14% of all fatalities on Polish roads, the issue is serious and requires more research and proper road safety treatments. Data for 2007 - 2016 show that in the case of accidents on horizontal curves app. 45% of the...
