Resumen:

This paper deals with the velocity control and compensation of dynamic friction in DC servo actuators with harmonic drives, in whose response nonlinear friction is very relevant. A control law is proposed that considers the use of observers and a novel second order dynamic friction model, that works in parallel with an adaptive law that explicitly includes friction compensation. Velocity and position tracking performance has been verified through experimental testing. © 2009 IEEE.
