This paper presents the mathematical model and control of a voltage source inverter (VSI) connected to an alternating current (AC) microgrid. The VSI considered in this is six switches three-phase Pulse Width Modulated (PWM) inverter, whose output active reactive power controlled dq reference frame. strategy presented here state feedback with disturbance cancellation. signal either provided by ...

The modelling of a three-phase four-leg four-wire grid-forming inverter in low voltage distribution system 18-bus European Cigré under unbalanced conditions an autonomous network is presented. case study has two types inverters control strategy: (i) to supply all the demand interval intentional interruption and (ii) grid-following integrate photovoltaic renewable energy resources into power sys...

This study investigates the efficacy of optimal semi-active dampers for achieving the best results in seismic response mitigation of adjacent buildings connected to each other by magnetorheological (MR) dampers under earthquakes. One of the challenges in the application of this study is to develop an effective optimal control strategy that can fully utilize the capabilities of the MR dampers. H...

This paper presents the mathematical model and control of voltage source inverter (VSI) connected to an alternating current (AC) microgrid. The VSI used in this work was a six-switch three-phase PWM inverter, whose output voltages were controlled synchronous (dq) reference frame via sliding mode strategy. strategy required only voltages; other states system estimated by using high-gain observer...

Exoskeleton robots need to always actively assist the user’s movements otherwise robot just becomes a heavy load for user. However, estimating diversified movement intentions in daily life is not easy and no algorithm so far has achieved that level of estimation. In this study, we rather focus on assisting limited number selected by using an EMG-based classification newly developed light...

In this paper, a new configuration for symmetrical and asymmetrical multilevel inverters is proposed. In asymmetric mode, different algorithms are suggested in order to determine the magnitudes of DC voltage sources. The merit of this topology to the conventional symmetric and asymmetric inverters is verified by the provided comparisons. This topology uses a lower number of power electronic dev...
