Control Strategies for Mechanically-Coupled High Speed Linear Drives

Abstract:

Vibration excitation of the machine structures caused by high speed drives often leads to production inaccuracies. By coupling two opposed driving and corporate acting linear drives in one drive train the static and dynamic properties can be improved. This arrangement offers the possibility to distribute the forces between both drives. Furthermore the impulse and jerk feedback into the machine structure can be minimized. In addition de-and acceleration energy can be saved in the coupling element. In order to guarantee the requirement for high accuracy in synchronous tracking as well as to realize pretension of both drives for high acceleration, control strategies and controller tuning methods are going to be discussed based on simulation results.
