PI-V plus Sliding Mode Based Cascade Control of Magnetic Levitation
Eroglu, Yakup; Ablay, Gunyaz (IEEE, 2015)Magnetic levitation systems are able to provide frictionless, reliable, fast and economical operations in wide-range applications. The effectiveness and applicability of these systems require precise feedback control ... -
A robust estimator-based optimal algebraic approach to steam generator feedwater control system
Ablay, Gunyaz (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, ATATURK BULVARI NO 221, KAVAKLIDERE, ANKARA, 00000, TURKEY Categories / Classification, 2016)Feedwater control systems are used to maintain the steam generator water level within prescribed narrow limits and to provide constant supply of steam during power demand variations. Current feedwater control systems are ... -
Robust estimator-based optimal control designs for U-tube steam generators
Ablay, Gunyaz (SAGE PUBLICATIONS LTD, 2015)U-tube steam generator level control systems are used to maintain the water level within prescribed narrow limits and to provide constant supply of high-quality steam during power demand variations. Traditional level control ... -
Robust integral controllers for high-order class-D power amplifiers
Ablay, Gunyaz (INST ENGINEERING TECHNOLOGY-IET, MICHAEL FARADAY HOUSE SIX HILLS WAY STEVENAGE, HERTFORD SG1 2AY, ENGLAND, 2018)This study presents variable structure system theory based robust integral controllers for class-D power amplifiers. These amplifiers are highly efficient switching type power amplifiers with negligible losses. Sensorless ... -
Robust reactivity, neutron source, and precursor estimators for nuclear reactors
Ablay, Gunyaz (ELSEVIER SCIENCE SAPO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2013)Reactivity, precursor concentration, and external neutron source strength determine control, operation and performance of nuclear reactors. These main reactor quantities are not directly measurable and must be calculated ... -
Steam Generator Level Control with an Observer-Based Algebraic Approach
Ablay, Gunyaz (IEEE, 2013)Level control systems are used to maintain the steam generator water level within the prescribed narrow limits and to provide constant supply of steam during power demand variations. The current level control systems are ... -
Variable structure controllers for unstable processes
Ablay, Gunyaz (ELSEVIER SCI LTD, 2015)A variable structure control (VSC) method for unstable industrial processes is proposed. The proposed control method is able to provide a highly satisfactory system performance and to tackle with robustness issues of the ...
