“…The Hagen-Poiseuille formula [43] may be used to calculate the leakage flow, which is derived from the presumption that it is linearly proportional to the pressure differential across the pump in Equation ( 6): (6) where μ = ν ρ. Since data sheets rarely include information on the mechanical efficiency of pumps, this efficiency is calculated from the total and volumetric efficiencies on the presumption that the hydraulic efficiency is negligibly low from Equation (7):…”

Due to its excellent energy efficiency and broad speed range, the variable-speed electro-hydraulic drive is an appealing driving principle in many contemporary industrial applications. It is a primary control of linear motion by a variable speed electric motor driving a hydraulic actuator via a constant displacement pump. One of the most commonly used controllers for the speed control of induction motors is Proportional Integral (PI) type. However, the traditional PI controller has some disadvantages such as the high starting overshoot, sensitivity to controller gains, and sluggish response due to sudden disturbance. To overcome these defects, an intelligent controller based on PI Fuzzy logic set theory is introduced to the electro-hydraulic system. This paper presents a study on the speed control of an indirect vector controlled induction motor driving an electro-hydraulic actuator. Various techniques of speed control like voltage-frequency control, sinusoidal pulse width modulation PI control, indirect field control, and fuzzy logic PI control were applied in the electro-hydraulic system and simulated by Matlab/Simulink environment for performance analysis and comparison. The results prove that the indirect field-oriented control technique with PI fuzzy logic controller provides better speed control of the induction motor, especially with high dynamic disturbances. This, in turn, will improve the performance of the proposed electro-hydraulic system.

“…Pri meraní hustoty sme zaznamenali lineárne klesajúci priebeh a pri dynamickej viskozite exponenciálne klesajúci priebeh s rastúcou teplotou. Podobné typy závislostí aplikovali vo svojich výskumoch aj iní autori (Kotia et al, 2019;Hashim et al, 2022;Sah et al, 2021;Liu et al, 2022) Technology, vol. 17, pp.…”

“…Podobný typ lineárne klesajúcej závislosti pri hustote dosiahli aj autoriKotia et al (2019), ktorí sa zaoberali reologickými a tribologickými vlastnosťami priemyselných prevodových olejov a zmenami na týchto olejoch vplyvom pridávania nanočastíc Al2O3 a SiO2. AutoriHashim et al (2022) zaoberajúci sa hydraulickými olejmi HL32 dosiahli taktiež lineárne klesajúci charakter závislosti hustoty od teploty. Saxena et al (2020) konštatovali tiež rovnaký typ závislosti, pričom autori sa zaoberali fyzikálnymi vlastnosťami prevodových olejov modifikovaných MWCNT/grafénovými časticami .…”

The thesis focuses on the measurement and identification of the dynamic system of a DC motor. The identification consists of measuring the number of revolutions of the DC motor, while changing the size of the motor power, and then performing a transfer function in the MATLAB computer program. The control unit consists of a C8051F342 microcontroller. The results of measuring the number of revolutions are performed by the computer program Terminal v1.9b. The conclusion evaluates the correctness of the measured results and the identified transfer function.
