Control structures for opposed driving, coupled linear drives

Abstract

In manufacturing linear motors are mainly used in the field of lightweight and highly dynamic drives. The high acceleration forces leads to vibration excitations of the machine structure that causes production inaccuracies. This can be improved by coupling two corporate acting and opposed driving linear drives in one drive train. The coupled structure can improve the static and dynamic properties by distributing the forces between both drives. In order to guarantee the requirement for high accuracy in synchronous tracking, control structures and controller tuning methods are going to be discussed based on simulation and experimental results. © Springer International Publishing Switzerland 2014.
