Abstract:
The dynamics of robots has to be considered as non-linear because of the couplings between the robot axes and the effects of the Coulomb friction within the joints. For the first type of non-linearities a state feedback control is often designed by the method of exact linearization and non-linear decoupling. ; But there are disadvantages of such control design: (i) exact knowledge about the system model is needed to avoid all the related sensitivity problems; (ii) discontinuous non-linearities, such as e.g. the Coulomb friction cannot be analysed by this method. Therefore two other design approaches are proposed: the method of "reverse linearization" and the method of estimation and compensation of non-linearities. They result in a robust independent joint control of robots.
