Vector control of single-phase inverter

What is a vector control in a single-phase inverter?

—A vector control based on the extended equivalent circuit and circuits virtualis proposed for the single-phase inverter. By the extended circuit, the other two phase voltages can be extended by the output voltage of the gle-sinphase inverter so as to construct the voltage vector. The voltage outer-loop is to control the voltage vector in
