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…

A DC-AC Three Phase Inverter Using Robust Control and LC Filter
—
by
This work describes a robust control approach for calculating controller gain. For a three-phase dc-ac inverter with an output LC filter, robust control techniques were used. The control rule is given in a synchronous dq frame and was developed using a discrete-time state space design approach. It integrates the tracking error and uses state feedback.…
