A small-signal model is used to design the controller parameters of the conventional Power Factor Correction (PFC) converter. The dynamics of the converter is nonlinear, therefore, it is hard to derive desirable performance. Genetic algorithm is used to optimize the control parameters of PFC converter in this paper, by this way, the quasi-optimal control parameters can be obtained with the predefined...
This paper presents the H∞ robust control law elaborated on the basis of a state-space averaged model of the Vienna rectifier, expressed in the synchronous rotating frame. A control scheme is designed by using the steady-state and dynamic models of the Vienna rectifier that are derived by means of a local linearization around the nominal operating point. The proposed robust control law is then verified...
