A　new　digital　closed　dual-loop　control　method　based　on　DSP　is　declared,　which　combins　the　single　modified　neuron　PID　control　strategy　and　non-deadbeat　control　method.　This　method　combines　the　advantages　of　PID　control　and　non-deadbeat　control.　Deadbeat　control　has　good　performance　at　high　control　precision,　and　PID　control　is　simple,　and　so　on.　By　the　way　of　simulation　on　Matlab/Simulink,　a　control　system　model　whose　target　board　is　TI2808　DSP　is　presented.　Automatic　code-generation　is　accomplished　from　this　model.　The　results　of　the　experiment　declare　that　the　control　method　of　the　inverter　receives　a　lot　of　advantages　such　as　a　good　and　fast　response　of　output　waveform,　curtate　developing　time,　and　reduced　its　developing　cost.
