Application of Internal Model Control to Current Regulation of Vector-controlled Induction Motor

In this paper, the internal mode control approach is applied to the current regulation of indirect rotor flux oriented control(IFOC) of asynchronous induction motor The design methodology of current regulator is presented and its dynamic and robust characteristics is analyzed using matrix singular values. The performance of IMC is compared with that of PI current regulation Finally, the simulating and experimental results verify the good performances of the internal model current control in the IFOC asynchronous induction motor.
