“…The control techniques offered in Khatib [1], Hsu et al [2], Canudas et al [3], Siciliano et al [4], Galicki [5], Kelly and Moreno [6], Nakanishi et al [7], Moreno-Valenzuela and Gonzales-Hernandez [8] require the full knowledge of the robot dynamics neglecting the external disturbances. Works Tatlicioglu et al [9], Sadeghian et al [10], Sadeghian et al [11], Feng and Palaniswami [12], Zergeroglu et al [13], Braganza et al [14], Braganza et al [15], Galicki [16], Cheah et al [17], Li and Cheah [18], Li and Cheah [19], Galicki [20] present adaptive control algorithms to compensate for parametric uncertainties in dynamic model including only the linearly parametrizable friction terms (viscous friction) and also neglecting the external (non-linearly parametrizable) disturbances. Moreover, control laws from Tatlicioglu et al [9], Sadeghian et al [10], Sadeghian et al [11], Feng and Palaniswami [12], Zergeroglu et al [13], Braganza et al [14], Braganza et al [15], Galicki [16], Cheah et al [17], Li and Cheah [18], Li and Cheah [19] use pseudo-inverse of either the exact or approximate Jacobian matrices.…”
