Abstract :
In this paper is done the experimental identification of friction parameters in LuGre model using the two degree of freedom controllers (TDOF). With identified parameters, friction compensation is implemented in SCARA industrial robot. For friction compensation is used a velocity observer. Controllers and friction compensation are implemented using the real time language XO/2. Analyses of experimental results for low velocities are presented.
