"Power Transmission and Motion Control (PTMC) 2005" comprises 32 papers presented at PTMC 2005 - one of a series of annual International Workshops held at the University of Bath. This collection of papers reports on the latest research in the fields of hydraulic and pneumatic motion control worldwide. The topics include: drives, transmissions and actuators; hydraulic and pneumatic components and systems; modelling and simulation; control; hydraulic fluids, including water and 'smart' fluids; fault analysis and diagnosis; noise and vibration; and system design. This volume will be of particular interest to researchers and practitioners working in the fields of power transmission, motion control, hydraulics and pneumatics.
