Position Tracking Control of Miniature Low Pressure Water Hydraulic Cylinders

Over the past 20 years research in the field of miniature actuators has increased substantially thanks to advances in smart material fabrication, semi-conductor chip technology and computer processing capability. Hydraulic cylinders offer many potential benefits as miniature actuators including: high power-to-weight ratio, mechanical stiffness, smooth motion and the potential for high positional accuracy. Despite their benefits the control of …
