The future of power systems depends on the microgrid (MG) which includes distribution generators utilizing Renewable Energy Resources (RERs) and storage facilities. Decentralized control techniques are more reliable stable in comparison with centralized controlled techniques. In this paper, a decentralized strategy is presented for an islanded AC MG system. improved droop virtual impedance. Con...

Aerospace industry has been involved in virtual simulation for design and testing since the birth of virtual reality. Today this industry is showing a growing interest in the development of haptic-based maintenance training applications, which represent the most advanced way to simulate maintenance and repair tasks within a virtual environment by means of a visual-haptic approach. The goal is t...

We obtain the existence and the uniqueness at the same time in the reconstruction of orthotropic conductivity in two space dimensions by using two sets of internal current densities and boundary conductivity. The curl free equation of Faraday’s law is taken instead of the elliptic equation in a divergence form which is typically used in electrical impedance tomography. A reconstruction method b...

Calibrating the VNA is an essential step that must be completed before doing any S-parameter measurements. The goal of the calibration is to define systematic measurement errors that will be further excluded from the DUT measurement results by the error correction procedure. In other words, the calibrated system has a virtual measurement reference plane located close to the DUT (at the probe ti...

The controller we developed for master-slave remote ultrasound diagnostics for an aging society has a variable impedance control capabi l i ty for master/slave manipulator positions. Diagnostic tasks are classified in remote ultrasound diagnosis, then methods and devices are proposed to change virtual viscosity based on diagnostic tasks. Remote ultrasound diagnostic experiments demonstrated tha...

In recent years a lot of versatile robots have been developed to work in environments with human. However they are not sufficiently flexible nor safe in terms of interaction with human. In our approach we focused on hand and eye coordination in order to establish a flexible robot control, in which a robot recognizes its environment from the input camera images and equips a soft contacting strat...
