摘要:
The paper deals with the theoretical modelling of the high performance Integrated Electro-Hydraulic Actuator (IEHA) introduced in the first part of this work. Based of the hydraulic and dynamic equations, we carried out an analysis of the IEHA input/output relation. A simulation based on this input/output model is detailed showing the ability to access several time derivatives of the payload position mainly its "jerk", which represents an important issue whenever motion control is considered. We show the theoretical dynamic properties of the proposed solution through open and closed loop simulation results based on Matlab-Simulink. A comparison between the theoretical and experimental results obtained by a built prototype is given in order to demonstrate the promising performances of the proposed solution.

摘要:
In this paper an experimental setup and experimental procedures which allow a fast and complete characterization of piezoelectric films continuously over the 1 Hz-1 kHz frequency range are reported. Some results related to PVDF electro-mechanical characterization are also presented. This work is intended as the first step for the electro-mechanical design of innovative integrated transductions systems for tactile sensors in robotic applications. The article concludes with a summary and a discussion of future investigations. (C) 2011 Published by Elsevier B.V.
