| Abstract: | According to the characteristic of three-phase inverter based on αβ rotating frame,this paper presented a control scheme of inverter output waveform control based on neural network internal model theory.The control scheme took a neural network estimate model as the internal model of three-phase inverter to estimate the actual output waveform.The simulation and experiment verify the scheme can work well.Highly accurate steady output,fast response and less distorted waveform is gained. |
| Keywords: | three-phase inverter inverter waveform control internal model theory neural network |
