Abstract

The scholars find great interest in matrix converter because of its great merits. But the researches mainly focus on open-loop control, and emphasis on the design of modulation strategy. Because the output and input lines are directly connected in matrix converter, the disturbance and unbalance of input lines affect the quality of the output waveform directly. Furthermore, in high efficient vector control systems, power converters are normally controlled to track reference output current in closed-loop. Apparently, it is necessary to control matrix converters in closed-loop. This paper establishes the model of matrix converters in d-q frame via PARK transformation. Since the closed-loop controller is relatively independent of the power electronic circuits, an automatic disturbance rejection controller (ADRC) for output current tracking is designed by applying ADRC algorithm to a matrix converter modulated by space vector modulation. Simulation results indicate that the controller have the advantages of good steady and - dynamic performances, and it is strongly robust.
