I need to develop a controller for three phase inverter. To design controller, first I need to know the mathematical model/transfer function of the 3-phase inverter.
The title are as mentioned MODELING AND SIMULATION OF A THREE-PHASE INVERTER WITH RECTIFIER-TYPE NONLINEAR LOADS and MATLAB / SIMULINK MODEL OF SPACE VECTOR PWM FOR THREE-PHASE VOLTAGE SOURCE INVERTER.
In addition to the reference above, I would recommend the attached book chapter that explains the modelling of different kinds of three phase inverters.
