| Abstract: | Additional nonlinear controllers are designed based on the exact linearization approach by state feedback. The control modes are constant AC voltage at the inverter and constant direct current at the rectifier. Furthermore, the good regulating performances of the designed controllers can be realized by using less local data. The simulation results show the dynamic characteristic of AC/DC systems can be improved effectively. |
