| Abstract: | This paper introduces the thinking of repetitive control using on the base of the mean value control of output voltage digital PID control of ac chopping.In this control system,the forward passage uses instantaneous compensation control,overcoming the output voltage transient variation that caused by power grid voltage transient or the load suddenly change,so the output voltage waveform is stable.In order to validate control method,the laboratorial platform has been built.Experimental results show that the method of instantaneous value compensation can suppress output voltage transient variation efficiently,and also prove that the output voltage is stable and reliable. |
