The hybrid control method is designed to combine all advantages that controllers have such as flexibility realized by fractional order calculation, robustness to disturbances and parameters variations provided by sliding mode controller (SMC) as well as adaptation of G constant of SMC via fuzzy controller, simultaneously. Also, a fractional-order SMC is applied to the system for the same reference speed and angle references to show the effects of the changes and adaptation of G constant. Experimental results show that the AFFOSMC has better trajectory tracking performance than the FOSMC.</p><p>DOI: <a href="http://dx.doi.org/10.5755/j01.eie.24.2.20630">http://dx.doi.org/10.5755/j01.eie.24.2.20630</a></p>}, number={2}, journal={Elektronika ir Elektrotechnika}, author={Orman, Kamil and Can, Kaan and Basci, Abdullah and Derdiyok, Adnan}, year={2018}, month={Apr.}, pages={12-17} }
