Two Adaptive Friction Compensation for DC Servomotors
Two advanced control strategies of adaptive friction Compensation For DC servomotor are presented in this paper, the first is used for The direct on-line friction compensation in the velocity control system, The second is making use of an adaptive inverse neural network controller In the position control system. Both are composed of an adaptive Compensator for the nonlinear stiction and Coulomp friction in Parallel with a
PID regulator. Experiments show that much improvement Of performance has attained respect to conventional controller.
