Phase and amplitude improving method and system thereof

A phase and an amplitude improving method, comprising:

• performing a model establishing step, wherein the model establishing step comprises configuring a processor to establish an inverter model corresponding to an inverter circuit, a voltage command is inputted to the inverter model to generate an actual voltage information, and the voltage command comprises a phase command information and an amplitude command information;
• performing a phase compensating step, wherein the phase compensating step comprises configuring a phase controller to receive the voltage command, and compute the phase command information of the voltage command and the actual voltage information to generate a compensating phase information according to a phase compensating program;
• performing an amplitude compensating step, wherein the amplitude compensating step comprises configuring an amplitude controller to receive the voltage command, and compute the amplitude command information of the voltage command and the actual voltage information to generate a compensating amplitude information according to an amplitude compensating program;
• and
• performing a compensation information generating step, wherein the compensation information generating step comprises configuring the processor to generate a compensating voltage command according to the compensating phase information and the compensating amplitude information, and the compensating voltage command is inputted to the inverter model to generate a compensating actual voltage information;
• wherein a difference between the compensating actual voltage information and the voltage command is less than a difference between the actual voltage information and the voltage command.
