Research on double closed-loop control strategy based on two-stage matrix converter

A voltage and current double closed-loop control method based on plural PI controller against two-stage matrix converter is developed. the compound vector models of the inverter side are established in d-q frame by introducing compound vector, a dual-loop control strategy which has the function of decoupling is presented accordingly by adopting the models, the plural PI controllers are designed to achieve the output voltage and output current control against the outside loop of voltage and the current inner loop respectively, and the models can be established by the SIMULINK. Simulation results show that the control method realizes a decoupling control and improves dynamic and steady performance and anti-jamming capability of TSMC.
