Research on Predictive Control Method of an Induction Machine Fed by a Matrix Converter

In order to get unit input power factor, and achieve decoupling control of the exciting component and the torque component of the stator current, the rotor field-oriented vector control of the induction machine and the predictive control of the matrix converter are combined. Double closed loop with flux and speed is adopted, and the stator current and reactive power are multi-objective predictive controlled. Simulation results verified that the predictive control method of an induction machine fed by a matrix converter not only retain advantages of the traditional rotor flux-oriented vector control of the induction machine, but also make advantage of the predictive control. The input power factor is at unity, the power quality is improved; The decoupling control of the torque component and the exciting component of the stator current is achieved, the dynamic performance of the speed regulation system is improved.
