Controller design for a nonlinear model of ball screw driven system considering disturbance input

In this paper, the controller is designed for ball screwdriven system which possess nonlinear friction, coulombfriction, which external disturbance represents this insystem. In addition, active vibration damping as well asposition controlling of ball screw driven system is carriedout by very simple and effective method which is shownin paper. The disturbance effects on system’s output areindicated by designing controller without consideringdisturbance and then comparing obtained results withthose of the whole system with disturbance. The outputdiagrams are shown for both systems, either withoutdisturbance or with disturbance. As it is indicated, thesettling time would be increased by consideringdisturbance in system.
