Research of the SPWM inverter in double loop control

摘要：

In the paper, we research the double loop control technique which are internal voltage and external number of the single-phase SPWM inverter current, establish a single phase full-bridge PWM inverter model, based on Pole Placement, it designs the Loop control parameters; in the digital control, In order to overcome the problem of limited duty rate caused by the digital processor sampling and calculation delay, here has designed a state observer and disturbance observer. The state observers output is affected by many kinds of errors, so we add a duplicate to reduce the errors. Finally, apply MATLAB to do simulation experiment, the result proves that Loop control system has both good static performance and fast response.
