Off-Board Charger for Electric Vehicle Using LMI-Based Optimizing Control

The proliferation of electric vehicles (EVs) has seen significant growth over the last decade, mostly attributable to their environmental advantages and versatile nature. This work introduces a systematic control design approach that utilizes linear matrix inequality (LMI)-based optimization for an off-board EV charger. In this study, a cascaded control scheme is proposed, which combines proportional…

A Linear Matrix Inequality Approach to Optimal Voltage Control of a Three-Phase UPS Inverter under Unbalanced Loads

Unbalanced loads are extremely prevalent in real systems, and they create power quality issues for the UPS system. To address this problem, this work provides an optimal voltage control scheme for a three-phase inverter using the linear matrix inequality method. In addition, the purpose of this controller is to provide a well-balanced three-phase sinusoidal voltage…

Linear Matrix Inequality-Based Optimal State Feedback Control of a Three-Phase L-filtered Grid-Connected Inverter

This paper discusses a systematic control design for a three-phase L-filtered grid-connected inverter using linear matrix inequality-based optimization method. A state feedback control is employed to provide stability to the inverter system and with the inclusion of integral control the offset error can be eliminated. In addition, the proposed control is implemented in dq-synchronous frame…
