Документ Nonlinear control of voltage source AC-DC and DC-DC boost converters(NTU "KhPI", 2017) Peresada, S.; Kovbasa, S.; Pristupa, D.; Pushnitsyn, D.; Nikonenko, Y.The nonlinear controllers for voltage source AC-DC and DC-DC boost converters are presented. It is shown that decupling vector control guarantees that reactive component of the line current vector exponentially decays to zero. As a result, the equivalent voltage dynamics of AC-DC and DC-DC converters is the same. The voltage control algorithm is based on a feedback linearizing concept and has been designed using a two time-scale separation method. The achieved weak interconnection between control loops allows making reasonable simplifying assumptions for resulting locally stable error dynamics. Nonlinear voltage controller has typical cascaded structure and provides partial linearization of the resulting voltage dynamics. Simulation and experimental results proof the effectiveness of the theoretical findings.
