    Badania elektromechanicznych zespołów napędowych zwałowarki ZGOT
    (Wydawnictwa AGH, 2009) Anuszczyk, Jan; Jabłoński, Mariusz
    Paper presents the results of laboratory and industrial testing of the caterpillar drives of the loading feeder of the spreader ZGOT-15400.120 working in the strip pit Szczerców of the KWB »Bełchatów« Mine. The electromagnetic and electromechanical transient states in the drive systems have been analysed. A new conception of sensorless steering algorithm modification in the CUVC bord controlling of converter has been introdused. After proposed solution the decrease of motors torque oscilations and mechanical vibrations in the low frequencies range of converter work was obtained.

    Współczesne algorytmy sterowania maszyn górnictwa odkrywkowego w przykładach aplikacyjnych
    (Wydawnictwa AGH, 2011) Jabłoński, Mariusz; Anuszczyk, Jan
    The article discusses the effects of our own service and start-up works, review and projects, carried out in years 2006-2010 in the areas of the of KWB »Bełchatów« quarry and KWB »Turów« quarry. While these work there were made several of studies and analysis of the solutions there were used in both the programming technique, communication and drive systems. Research was focused on the KTZ system machines and their working conditions. All this was supported by graphical verification. Studies carried out in the article consists mainly of inverter drive systems and drive motors control algorithms of the traverse, rotation and lift either using a speed sensor or sensorless. During the research, there was carried out several working tests at working mining machines, and modifications of control algorithms implemented for commercial inverter systems software, PLC and HMI systems responsible for the drive work of testing machine. The main purpose of all the work was reducing of jittering and vibration during machine operation and ensuring a high level of operational reliability of the solutions, improving of mobility and safety.
