In physics-based sound synthesis, it is generally possible to incorporate a mechanical or acoustical immittance (admittance or impedance) in the form of a digital filter. Examples include modeling of the termination of a string or a tube. However, when digital filters are fitted to measured immittance data, care has to be taken that the resulting filter corresponds to a passive mechanical or ac...

Abstract. This paper proposes admittance matrix models to approach the behavior of six modern multiport functional blocks called: differential difference amplifier, differential difference operational floating amplifier, differential difference operational mirror amplifier, differential difference current conveyor, current backward transconductance amplifier and current differencing transconduc...

This paper proposes a recursive, virtual admittance based, secondary controller for DG units that improves the voltage profile in distribution networks. First, adaptation of concept goal regulation is explained. Then, recursive developed to periodically update gains. The formulated as an optimization problem with current and stability limitations constraints. Measurements across grid, transmitt...

This document addresses the problem of ruling a soft transition of an existing archive to an externally managed preservation environment. When such a transition must take place, the archive management has to decide whether to hand over the complete custody of its data holdings and/or its procedures to the preservation system, or to retain control of any of these, and, if so, to what extent. We ...

In this paper we present recent experimental results using a novel parallel manipulator operating under Natural Admittance Control performing difficult mechanical assemblies. The example assemblies are components from an automotive automatic transmission. Success depends on appropriate force responsiveness, rather than precise position control. The robotic assemblies are shown to be gentler tha...
