Abstract :
The main aim of this paper is to present a new start-aid method to control servo drive in case of very small velocity and distance changes are required. Using resetting of integration in the position controller and friction compensation as well as the initial phase correction - start-aid methods are compared and results of simulations are presented. Moreover, models of the drive and friction are delivered and schemas of control systems are presented.
