Abstract
A control system for a three-phase inverter includes an instantaneous value voltage controller and an equivalent effective value voltage controller. The instantaneous value voltage controller is configured to feed back and control an instantaneous value of an inverter output voltage. The equivalenteffective value voltage controller is configured to perform an orthogonal decomposition feedback control on an effective value of the inverter output voltage. The equivalent effective value voltage controller is configured to perform integral compensation respectively on a real-axis voltage and an imaginary-axis voltage of a two-phase rotating coordinate system of the three-phase inverter. An output of the instantaneous valuevoltage controller and an output of the equivalent effective value voltage controller are used to obtain the inverter output voltage through a delay stage transfer function and a controlled object transfer function.
