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

LMI-Based Robust Voltage Regulation of a Single-Phase Inverter with LC-Filtered Output
—
by
This paper presents a linear matrix inequality-based robust control strategy for a single-phase DC-AC inverter with output LC-filter. An all-pass filter is utilized in this paper to create an artificial β-signal so that the proposed controller can be simply used in dq-synchronous frame. This proposed robust controller utilizes a state feedback control with integral action…
