Approach for a fast automatic Control of Drive with elastic shaft

摘要

Laser beams can be deflected to desired positions by means of rotating mirrors. The deflection speeds required today high control dynamics for mirror positioning (mirror angle). This is done by means of electric miniature drives. Due to the fast adjustments, natural resonances of the actuator due to elastic deformations play an increasingly important role. The approach presented here describes how state space control can be supported in order to reduce the resonance effects in the position value.
