“…Among these methods, sliding-mode control is commonly used to reduce the dependency on a model (de Castro, Araujo, & Freitas, 2013;Harifi, Aghagolzadeh, Alizadeh, & Sadeghi, 2008;Lin & Hsu, 2003;Subudhi & Ge, 2012). Moreover, a class of fuzzy/neural network controls and their combination with adaptive approaches (Ćirović Contents Mirzaei et al, 2005;Sharkawy, 2010) have been used for adaptive prediction of wheel slip. In addition, feedback control (Mirzaeinejad & Mirzaei, 2010;Tanelli et al, 2008), iterative learning control (Mi, Lin, & Zhang, 2005) and extremum seeking control (Dincmen & Güvenc, 2012;Dincmen et al, 2014;Zhang & Ordóñez, 2007) are applied in this field.…”
