We report a web service for flute players, ‘The Virtual Boehm Flute’, that provides alternative fingerings which may be easier to play, less awkward to finger and/or more in tune for different circumstances. It also provides possible fingerings for multiphonics (chords). It uses an expert system that predicts the playability of notes from features in the input impedance spectra, based on the pl...

This paper focuses on a hybrid islanding detection algorithm for parallel-inverters-based microgrids. The proposed algorithm is implemented on the unit ensuring the control of the intelligent bypass switch connecting or disconnecting the microgrid from the utility. This method employs a grid impedance estimation technique that uses resonance excitation once grid fault occurs. It includes two st...

A novel power hardware-in-the-loop interface algorithm, the Virtual Shifting Impedance, is developed, validated and demonstrated in this paper. Building on existing algorithms, method involves shifting a part of software impedance to hardware side improve stability accuracy setups. However, compared approaches, realized by modifying command signals amplifier controller, thus avoiding requiremen...

Power flow control is one of the most important issues for operating the inverter-dominated autonomous microgrid. A technical challenge is how to achieve the accurate active/reactive power sharing of inverters. P-F and Q-V droop control schemes have been widely used for power sharing in the past decades. But they suffer from the poor power sharing in the presence of unequal line impedance. In o...

A haptic interface plays the important role of connecting the user to the controller during interactions with remote and virtual objects. Such systems incorporate mechanical, electrical, and computational elements, which all interact to create the touch-based sensations experienced by the user. This document is concerned specifically with actuated impedance-type interfaces, which currently domi...

The work presents the power-sharing in a standalone low voltage AC microgrid consisting of three parallel grid supporting inverters using virtual impedance-based droop system. Typically, isolated microgrids suffer unique challenges regarding voltage, current, frequency regulation, power flow control, and due to absence stiff source. This investigated sharing technical inverter-based distributed...

In recent years haptic interfaces (also know as manipulanda and hand controllers) have been developed for an impressive array of applications. For instance, Mussa-Ivaldi e t al. [ 181 describe a two degree of freedom manipulandum for studies of multijoint human limb movement, Adelstein and Rosen [ 11 a two degree-of-freedom manipulandum for studies of involuntary tremor, and Jones and Hunter [1...

Abstract In order to approach the performance of biological locomotion in legged robots, better integration between body design and control is required. that respect, understanding mechanics human will help us build robots with comparable efficient performance. From another perspective, developing bioinspired can also improve our locomotion. this work, we create a robot blended physical virtual...
