Positive Stage Jerk Feedback Combined with Positive Base Plate Jerk Feedback to Improve the Positioning Speed of a Pneumatic Stage

In this paper, a unidirectional positioning stage which is supported by four coil-type spring isolators and actuated by four pneumatic cylinders is Energy Bars considered.The stage jerk feedback scheme (SJFB) with positive polarity is proposed to reduce the stage mass, resulting in the improvement of positioning speed.However, reduction of stage ma
