Special Issue Information

Dear Colleagues,

The journal Actuators (ISSN 2076-0825; CODEN: ACTUC3, Scopus indexed, IF = 1.957) is currently running a Special Issue entitled “Recent Advances on Servovalves”.

Prof. Dr. Paolo Tamburrano, Prof. Dr. Riccardo Amirante, Prof. Dr. Elia Distaso, and Prof. Dr. Pietro De Palma are serving as guest editors for this Special Issue.

The articles in this Special Issue will be concerned with one of the most important topics in the industry, aerospace, and transportation sectors: servovalves. This term includes single stage (direct drive), two stage, and multi-stage electro-hydraulic and pneumatic valves. This Special Issue invites contributions dealing with the following: reviews of recent advances in industry and academia; analysis of the current issues of servovalves using numerical and/or experimental approaches; proposals and studies aimed at overcoming the issues and drawbacks of commercial designs; novel actuation systems for servovalves based on smart materials (e.g., piezo-electric actuators); improved control systems; novel valve architectures for improving performance or other aspects; and novel or improved empirical, numerical, and CFD approaches to study certain aspects of these valves.

The submission deadline is 31 August 2021. You may send your manuscript at any point from now until the deadline. Submitted papers should not be under consideration for publication elsewhere.

This paper presents a feasibility study using commercially available amplified piezo-stacks for the direct actuation of four-way three-position (4/3) direct drive servovalves. The prospect of using amplified piezo-stacks in place of linear force motors is very attractive by virtue of their fast response speed and low weight. Piezo-stacks equipped with mechanical amplification systems can give levels of displacement suitable for this application. A very effective amplification system has recently been produced by some manufacturers and is based on a temperature-independent diamond structure. This paper details simulations of a 4/3 servovalve directly actuated by such a piezoelectric actuator with a diamond structure. To this end, well-established equations, implemented in Simulink by means of the libraries of Simscape Fluids, are used. The proposed architecture shows simplicity of construction; in addition, very good step response speed and frequency response are predicted by the simulations. Full article
