Abstract :
This short note points out an improvement on the robust stability analysis for electrically drivenrobots given in the paper. In the paper, the author presents a FAT-based direct adaptive controlscheme for electrically driven robots in presence of nonlinearities associated with actuator inputconstraints. However, he offers not suitable stability analysis for the closed-loop system. In otherwords, it does not consider the role of saturation function in both control design and stabilityanalysis.
