This paper presents a controller design for a threephase controlled rectifier using artificial intelligence techniques to regulate the DC-bus voltage. The averaging model of the power electronic system is used as an objective function instead of the model from software packages. The averaging model is derived from the DQ modeling approach in which the dynamics of the transmission line and power converter are taken into account for the controller design. The results show that the proposed method can efficiently obtain the best performance of the output waveform compared with the classical method. Moreover, this approach is convenient and flexible for electrical engineering to design the controller of power electronic systems with the best output performance.
