This paper introduces a digital closed dual-loop control method based on the single modified neuron PID control strategy and the deadbeat control method in single-phase inverter. This method combines the advantages of PID control and non-deadbeat control, such as high control precision and simple control method and so on. By the way of simulation on Matlab/Simulink, the results of the experiment declare that the control method of the inverter in different operation modes receives a lot of advantages such as fast dynamic and static response character and good output performances.
