Power Transmission and Motion Control: PTMC 2004

Power Transmission and Motion Control 2004 (PTMC) comprises papers by authors from twelve countries.

Presented at PTMC 2004- one of a series of annual Workshops held at the Bath University- this collection of well illustrated papers reports on latest developments from key international research centres in the fields of hydraulic and pneumatic motion control.

Topics include:

• Drives, transmissions, and actuators
• Hydraulic and pneumatic components and systems
• Modelling and simulation
• Control
• Hydraulic fluids
• Condition monitoring
• Noise and Vibration
• Actuation systems
• Hydraulic system design
• Measurement techniques

Essential reading for researchers and practitioners working in the fields of power transmission, motion control, hydraulics, and pneumatics.
