Hydraulic Axis Actuation Control for Precision Motion
Authors: shalabi El Shalabi, robert whalley, M. kambiz Ebrahimi, Byron mason
Abstract
A new design for machine tool axis traverse, by hydraulic cylinder with spool and needle valve actuators, is presented. Regulation procedures enabling the formulation of a least effort control strategy are proposed. System integrity in the event of actuator failure is examined. Correspondingly, the maintenance of closed-loop stability, following feedback transducer loss, is also secured, demonstrating fail-safe, multivariable, feedback control. The suppression of the effects of disturbances and the response of the system to deterministic inputs is presented. Comments on the practicality of the design are incorporated and the mandatory specification of control system integrity is advocated.

Dear authors and all other conference participants,
Welcome to the robotics session of this IPROMS 2008 conference.
My name is Ze Ji, and I am the co-chair of this session.
If you need any assist regarding this session, please feel free to contact me via email: JiZ1 (at) cf.ac.uk.
First, I would thank the authors for contributing to IPROMS 2008.
For this paper, I have realised that the video has not been uploaded. Could the authors please prepare a video presentation and upload it? This will be helpful for others understanding your paper better. Here is the instructions on how to create a video presentation
In order to access the full text papers and video presentations and other functionalities, all conference participants are encouraged to register on the IRPOMS website online for free.
You are very welcome to post questions after reading the papers, and I believe the authors will be there very happy to answer you.
I hope you will enjoy this session.
Kind regards,
Ze Ji

Dear authors,
Thank you for this very interesting work. Was the output of your research implemented in a commercial context by a equipment manufacturer?
