Title: METHOD AND DEVICE FOR PROCESSING INVERTER SAMPLING SIGNAL, AND INVERTOR CONTROL SYSTEM
Abstract:
The present invention provides a method and device for processing an inverter sampling signal, and an inverter control system. The method comprises: acquiring a first output signal output at a current moment by an inverter; obtaining a second output signal output at a last moment by the inverter; generating a compensation output signal corresponding to the first output signal according to the first and second output signals to allow an inverter controller to obtain, according to the compensation output signal, a control signal used for adjusting the inverter to output a third output signal at a next moment. The method and device for processing an inverter sampling signal and the inverter control system provided by the present invention can improve the control precision of the inverter control system.
