Voltage Sensorless Control of a Three-Phase Standalone Inverter based on Internal Model Control
Abstract
Steady operation of a converter as it undergoes a voltage sensing failure requires the development of smarter control algorithms with special qualitative features which can well accommodate the uncertainties. In this work, a backup control scheme based on the internal model principle in the absence of the output voltage sensor for a standalone three-phase inverter has been proposed. This methodology incorporates an estimation of the output voltage which is provided based on current information and the output ac capacitor value which can cancel the dependency of the inverter performance on the information provided by the voltage sensors. The overall approach has been implemented in a scaled-down physical distributed generation (a standalone inverter) based on HiL (hardware-in-the-loop) real-time co-simulation using Xilinx System Generator platform to further verify the accuracy of the system.
