satisfactory response and loop performance may not be
simultaneously accomplished. The achievement of one
compromises the other.
In the present work, two degree-of-freedom (2 DOF) control
scheme as shown in Fig. 2 is employed to achieve the output
voltage regulation of boost converter. The aim of applying 2
DOF control is to have satisfactory robust stability, disturbance
rejection properties as well as to obtain desired output response
since this controller processes the reference and the feedback
signals differentially.
