- The close loop current control consists coupling terms with PI regulator in d & q component of the current. All these current loops based on reference transformation (like DQ-abc) so on & Phase locked loop so on, that is quit complex thing can be make accurately model as transfer function of second order. The current control model will be compared to the equivalent closed loop current control transfer function by applying the second order system. By this technique, easily can be calculated PI regulator control gain. Then apply the unitary step response for comparing the result between the current control loop & equivalent current control transfer function. Finally, we will be applied the inverse-Laplace transform, where the dynamic behavior is given by natural frequency into the exponential term.
