Abstract

To decrease both the number and tuning difficulty of weighting factors, an advanced model predictive current control is proposed for an induction motor drive system fed by an indirect matrix converter, where the input and output currents of the indirect matrix converter are designated as control objectives. The reference input currents are established on the basis of the instantaneous power theory and optimized using a low-pass filter. In addition, the reference output currents are determined using a reference flux vector based on the deadbeat theory. As a result, there is only one weighting factor for parameter tuning, and the predictive models are significantly simplified. In addition, both the phase and the quality of the input currents are considered and controlled, which can improve the grid power quality. Simulation and experimental results show that the sinusoidal grid/output currents, a unity power factor, and good steady-state and dynamic performances of the induction motor have been achieved. In addition, the execution time of the entire algorithm was noticeably shortened.
