A highly integrated low pressure fluid servo-valve for applications in wearable robotic systems
In Proceedings of 7th International Conference on Informatics in Control, Automation and Robotics, (ICINCO-2010), 15.6.-18.6.2010, Madeira, o.A., Jun/2010.
In this paper an innovative low pressure proportional valve is presented. The device was designed with the main aim to be easily integrated into complex hydraulic/pneumatic actuation systems, and to operate at relatively
low pressure (< 50 · 105Pa). Characteristics like compactness, lightweight, high bandwidth, and autonomous sensory capability, where considered during the design process, this in order to achieve a device that
fulfill the basic requirements for a wearable robotic system. Preliminary results about the prototype performances are presented here, in particular its dynamic behavior was measured in different working conditions,
and a non-linear model identified using a recursive Hammerstein-Wiener parameter adaptation algorithm.
